Thanks a lot for the image and the information you sent. I put them in our site (http://www.isfahan.ir/kamaneasemani/news/810917.html).
I have a very important question:
Negative age of the Moon Crescent you observed in the morning of January 19, 1996 was -21hours 35 minutes (at 15:08 UT). On the other hand, positive age of the Moon Crescent you saw in the sunset of January 20, 1996 was + 12 hours 07 minutes (http://www.isfahan.ir/kamaneasemani/lec/stamm.html). Therefore, the time interval between observing the last morning crescent and the first evening crescent will be 33 hours 47 minutes. We believe this to be a global record. Did you know this?
Before, we had thought that this record was 35 hours 20 minutes belonging to an Iranian observer. Please let me know your viewpoint in this regard.
Have a good time,
