Dear Professor.  Sinnott                                           Happy new year

 

 

 

 

As we already informed you, different groups in Iran with very sophisticated equipments tried to sight the lunar crescent on 7th September 2002. Only one group managed to sight it and the other groups faced unfavorable atmospheric conditions. With this sighting we achieved a new world record of which we have the full report including the related table and photos. This report is a little late in getting to your hands because of tow reasons:

 

1- For confirmation in Iranian search centers and organizations.

 

2- We waited for the Ramadan lunar crescent sighting, which in turn can make modifications in international standards for lunar crescent sighting.

 

A copy of this report is sent to professor (Yallop), professor (Ilyas) (SAAO) the As South African Astronomical Observatory.(ICOP) Islamic crescent observation project.

 

 

 

A  New World Record For lunar Crescent Sighting. 

 

 

We were in an arid region located on height north west of Zarand in Rashk Bala village, (31°,04'N) (56°,28'E) 105 Kilometer north west of Kerman town (most important city in south east of Iran), 2110 M altitude, settled there with strong and powerful optic instruments containing: one Newtonian 8 inched telescope Vixen model, 30 mm wide eyed, two huge binoculars ( 20x120 ) Reek model, a very giant binocular ( 40 x150 ),all trimmed on western horizon to hunt a very rare slender lunar crescent, and we were ready to start lunar crescent sighting after sunset.

 


 

 

(we have already done our best efforts to sight the new moon crescent on 22nd Des 1995 How ever all the conditions of sighting were  excellent and the western horizon was clear but because of our not powerful binoculars (20 x 60),(12 x 45 ) we couldn't sight that precious crescent. Since then we decided to use extra powerful instruments in future.)

 

  

 

Based on our previous calculations, we had been soured sighting this lunar crescent in most part of Iran, as eastern, central, southern and southeastern parts of Iran, would break the world record of sighting new young lunar crescent. We studied all the world records and new that Mr. James Stamm has the best record in the world so far. He has succeeded to sight new lunar crescent, angular separation 7°.39' (topocnetric),12hours,7minutes,through 8 inched telescope.(Celestrone mark) in Tucson Arizona USA, on January 20th 1996 at local time. Regarding Mr. Stamm’s record, minutes after his sighing, two other amateurs sighted the same lunar crescent. One of theme” Mr. Pear Shovar”12 hours 33 minutes through Newtonian 10 inched telescope and the other, Mr. Dana Pachik in Mount Wilson of USA, 12 hours 51 minutes through binoculars 11x 80. (Sky & Telescope)

 

 

 

These two reports also helped Mr. Stamm’s record to be more confirmed than any other reports.

 

Sighting new young lunar crescent at the beginning of the new lunar month is an interesting endeavor near Muslims. First visibility of new lunar crescent marks the beginning of new lunar month. In same manners, sighting new lunar crescent at the beginning of Ramadan lunar month fasting and sacred month in Muslims calendar, is of critical importance as well as sighting new young lunar crescent at the beginning of Shawwal lunar month which marks the greatest annual religious of Muslims.

 

Again, sighting new lunar crescent at the beginning of Zul-Hijja Lunar month marks the start of series of annual religious by millions of Muslims in Mecca, Saudi Arabia. All these important religious events in Muslim's lunar calendar are determined based on sighting new lunar crescent at the beginning of related lunar month which makes the moon sighting become an important endeavor in Islam history. I personally have decided to do sighting of new moon careful at the end of old or beginning of the new lunar month for 11 years. I have set a couple of records compared to formal world records, however I was not familiar to forward them to you in order to be confirmed and be published formally and distributed among astronomers. I am providing you a list of time table lunar visibilities in the past 8 years, at the end of this report.

 

At present the record of new lunar crescent sighting belongs to Mr. Steven N. Shour. He has sighted new young lunar crescent by his naked eyes on 5th may 1989 at local time. However the South African Astronomical Observatory (SAAO) has not confirmed his report yet. We were ready to set a new world record on 7th Sep 2002.We has been programming to accomplish this purpose from long time ago. A government institution (Iran center of strategic researches and programming) decided to dispatch several lunar observatory groups, equipped with all the modern equipments & tools needed for lunar observation to different parts of Iran, on 7th Sep 2002 in order to sure the real sighting of lunar crescent at the beginning of new lunar month.

 

·        First group equipped with three sets of powerful binoculars among other tools and equipments, to eastern parts of Iran.

 

·        Second group equipped all observatory instruments, to south eastern of Iran.

 

·        Third group equipped with complicated observatory equipments, to central part of Iran.

 

·        Forth group equipped with complicated observatory equipments, to southern part of Iran, Fars province.

 

Its worth mentioning, thirty (ABT) other private armature groups interested in observation lunar crescent, have set out to different and various parts of Iran, on their own decision.

 

We belonged to second group on mission to southeastern of Iran, Kerman province. Our group consisted of thirteen colleagues. Seven participants of this group have come from Kerman, and were very familiar with roads akd situation of heights and villages of Kerman province.

 

I personally moved to Kerman town on 1st sep 2002(6days prior to new moon date) in order to determine the best place suited for observation and settling the site. Based on gathering information about heights of Kerman province we came out with 5 named places as under:

 

1- Jibal Barez region (Mohammad Abad), 167 kilometers southeast of Kerman town.

 

2- Baghabar region, 90 kilometer of Kerman town, 2640 m altitude.

 

3- Bid kheiry region, 108 kilometer southwest of Kerman town, 2600 m altitude.

 

4- Bibi Hayat region, 50 kilometer northwest of Kerman, 2150 m altitude.

 

5- Rashk Bala region (village) located in Zarand province, 105 kilometer North West of Kerman town, 2110 m altitude.

 

We were sure should we sight the new young lunar crescent, on 7th Sep 2002 would bring us the record of age of new moon sighted ever. Therefore we were calmly and conveniently continued our studying information about different places and carefully compared all data with each other. We would like to choose a place helping us best to break the records of sighting new lunar crescent regarding age of moon and the degree of separation moon from conjunction.

 

We are aware of Mr. Andre Donjon's viewpoint of that no illuminated portion of moon arc can be seen when its separation is less than 7.fortunately calculations showed us on 7th sep the ecliptic latitude of moon was in its best position and also on 8th Sep 2002, at 3 hour UT, the moon would be in its perigee; and this made up hoping to reach to a new record.

 

Among factors we studied in order to compare them to decide the best place for our ultimate site, was accessibility of places to road connections. Fortunately after careful examination of details we learned that all 5 places are accessible to road and transportation network in Kerman province and we could easily transport our equipment to the mountain top or near of top of mountain. Other factors which affected our decision making to choose the best place was: geographic, atmospheric possibilities horizontal visibilities and weather conditions of 5 places to be considered and compared. On 5th Sep 2002, we sighted old lunar crescent, at 13 hours, 22minutes (local time) 24°, 50' separation from sun, by naked eyes in a very clear atmospheric condition, in Kerman. It should be mentioned that at that time the altitude of moon from horizon was 45°, 49'  (topocentric).We were very happy to see the situation like that and predicted that there would be no problem on 7th sep 2002.However in the afternoon of 5th sep 2002 the weather changed cloudy which worried us too much. We contacted repeatedly that day with meteorological administration to obtain meteorological data. So far that we had been informed apparently a front air with low pressure covered Saudi Arabia sky passing through Iran atmosphere.

 

Confronting a high pressure weather covered northern part of Iran, the result was some climatically changes in central and southeastern regions of Iran. On 6th Sep 2002, at dawn, I was ready to sight morning lunar crescent. I was aware that there was no need to any binocular to sight this old lunar crescent, since the separation angle of moon from sun would be 15°, 14' at the time of rising lunar crescent, as well as 2% luminosity (phase of moon).It is worth mentioning that presuming negative old age of moon 26h 31m.This would be an advantage for observers of moon arc in western hemisphere especially for western part of USA. Calculations showed us an observatory could succeed to sight old lunar crescent aged about 15 hours before conjunction of moon-sun and reaches to a dawn sighting record. However later I was informed with Mr. James Stamm has tried to sight that morning old lunar crescent but failed, unfortunately.

 

At last on 7th Sep 2002 we called on meteorological administration and requested them to advise us just on visibility factor. They suggest us “Rashk Bala”village located in Zarand province.

 

Our group moved to Zarand province and had lunch in Zarand. We waited to receive our optical equipment and other instruments. Our group and equipments started to jury to Rashk Bala which lasted about 2 hours. We all settled in a point on western horizon before sunset. Western horizon was open viewed and the altitude of encumbrance in the western horizon was less than 0.5°.Some atmospheric dust was seen in horizon which could not make us worry. We started setting binoculars & telescope .Our binocular were equipped with altimeter& goniometry. Since we had not knew where we would ultimately set up our site then could not actually use our telescope and type was not polar. We relied too much on our 40X150 binoculars. We knew its possilities. Based on computerized computations of local coordinates of sun & moon have been prepared and ready to use. We have observed sun through special sun filter and set our binoculars. It should be added that this setting of binoculars was continually done each 15 minutes till the sunset. In order to lower the error percentage of our observatory activities. The sun set at 18 hours 00minute 33 second. We were noticed some clouds appeared in western horizon; however its altitude from horizon hardly reached to 1 degree.

 

I positioned myself behind 40x150 binoculars while Mr. Sayad, my co assistance whose job in geophysics Institute of Tehran University is searching expert, having experiences computing sighing lunar crescent for 21 years, was setting the azimuth and altitude of binoculars based on computerized data each 2 minutes. Two colleagues of our group were sighing the western horizon the same manner just as I was. With two 20x120 binoculars, working with two co assistants. Also two other colleagues of our group were trying to sight through telescope. After sunset, all binoculars were trained toward the direction where the lunar crescent might be sighted. In order to Eli minate extra day light which might would come to my eyes and would prevented me from clear sighting, I covered my head stickled to binoculars under a blanket. I noticed a celestial body just where the lunar crescent might be at 18 hours 17 minutes after sun set .I could hardly felt the lunar crescent. Since I am used to sight three times by opening and closing my eyes to be sure about my sighting , this time I could not repeat my first sighting in second opening of my eyes ,so I invited one of my colleagues to come behind my binoculars. He left binoculars without success. I continued sighting in same manner I described earlier. At 18 hours 20 minutes I sighted clearly the slender lunar crescent; however the atmospheric dust did not permit me to sight constantly. Again at 18 hours 21 minutes I sighted the lunar crescent of moon, this time my visibility became clear. Sometime the laminated arc of moon was sighted very clear and sometime the wind brought the atmospheric dust to my vision and the lunar crescent become faint. I followed this lunar crescent for one minute. This lunar crescent was hidden under a layer of cloud, there was in horizon, then it was disappeared for good, at 18 hours 22 minutes. Without any delay, we measured the altitude of encumbrances in the horizon which was 1° 36'.Then I separated from my group to have some privacy. I felt sad and I was at the same time happy in my heart. My sadness rooted in not sighted the lunar crescent by my colleagues and my hearted happiness was about my success in sighting lunar crescent. I have to add that I am working as amateur slighter for eleven years and have enough experiences to be able to distinguish lunar crescent from smog, dust, illumination, airplane or any other celestial body in the sky.

 

I have sighted about 213 new and or old moon after and or before sun-moon conjunction time. Generally I have been successful in 73% of tries to sight lunar month during past years. The reason for my negligence in sending my reports to international scientific authorities is mere lack of communication with these scientific centers.

 

Moon sighting has been my favorable and lovely hobby in my life. I sight moon every day and note down the changes of moon for each day of lunar month. I would dare that I love the moon. I will give you some report I have obtained in Iran during my sighting in past8 years.

 

 

 

Time table:

 

Dawn sighting of lunar crescent of 30th Jan,1995,negative age of moon 19 hours 40 minutes, by naked eyes.(35°, 44' N) &( 51°,  17'E )

 

New lunar crescent sighting on 31 Jan ,1995,15hours 40 minutes age, through 12x45 binocular,(35°, 44' N) &( 51°, 17 'E).As you may well be aware should we calculate the negative age of moon on 30th Jan 1995 and add it to the age of new lunar crescent at the time of first visibility, then we would come up with 35 hours 20 minutes, which so far that I have studied the world records for moon sighting issued by “SAAO”. Till the end of 2000, have noticed no such record (I.E.35 hours 20 minutes. Bye till next visibility).

 

Dawn lunar crescent sighting (before conjunction of moon-sun), on 16th Oct 2001 (52°, 15' E) & (35°, 39' N), negative age 17 hours 10 minutes, by naked eyes. It should be mentioned this sighting has been filmed with usual handy camera. So far that I have studied the list of sighting records issued by “SAAO”, there is no such record booked. I Eva record of sighting dawn lunar crescent, age 17 hours 10 minutes, by naked eyes.

 

Dawn lunar crescent sighting, on 8th Aug 2002 (35°, 44' N) & (51°, 17' E), 17 hours 40 minutes age through 12x45 binoculars. I have filmed this crescent with my handy camera, in a special way of filming. For the reason of weather in east horizon not suitable to filming and existing some clouds in sky, I set the camera on negative position, and then the foreground became with clear and the crescent black. It should be mentioned one of Iranian moon observers in Esfahan has sighted this moon, age 17 hours 37 minutes through 12x70 binoculars and filmed it I will send you  my sighting results  in recent years which some of them are records in this area as I prepared in table 2.
