The geocentric new Moon will occur on Saturday 15 May 1999, at 12:05 UT. The program Moon Calculator by Dr. Monzur Ahmed -according to Ilyas' criterion- showed that the crescent will be visible by naked eyes on 15 May some where starting from Hawaii (USA). And so, countries west of this area will be able to see the crescent on this day. However, using telescopes, the crescent will be seen in more eastern areas. But since there are no countries in that region, so GENERALLY the crescent will be visible by naked eyes only on 16 May from everywhere in the world. Consequently, arrange to observe the crescent after the sunset of 15 or 16 May. Kindly click on the below icon to see the visibility parabola as plotted by the program Moon Calculator
When to Observe ?
Results of seeing the crescent, and the first day of Safar in different countries will be added here as we receive the reports from ICOP's members. If you wish to be a member in ICOP, or to know more about it, kindly click here.
During the 25th astronomical camping for JAS in Al-Azraq desert, we decided to glimpse the very thing waning crescent of Muharram 1420 AH on 14 May at the East before sunrise. The TOPOCENTRIC -NOT GEOCENTRIC- Moon's age was 'minus' 35 hours and 16 minutes. The Moonrise occurred at 03:55, at which we started the observation, and with much happiness I shouted at 04:10 saying .... Here it is !! It was firstly visible by binocular 7X50. We pointed the telescope at the crescent, and so all the observers saw it. After few minutes Mr. Hani Al-Dalee' surprised us by saying:... I can see it by naked eyes !!
Actually it was not that surprise to see such 'relatively' big crescent, but what we managed to know is how long time we will be able to see the crescent ? Will we be able to see it after the sunrise ??
The apparent sunrise occurred at 04:38, which is the same time at which the last observer was able to see the crescent by naked eyes ! But it was still visible by telescope, and we kept tracking it by motor drive for 45 minutes after the sunrise ! Then it was about to leave the field of the telescope ! We had two choices; either to leave it to leave the field, or to try to get it back to the center, but that was a VERY hard job, because it was very very barely visible, and any error could get it lost ! Unfortunately, this what happened ! I believe we were able to track it more, but I guess what we achieved is fine ! Kindly see the below photo for the observed crescent.
The observers were:- Hani Al-Dalee' (ICOP), Khalid Tell (ICOP), Moh'd Odeh (ICOP), Mohammad Murad (ICOP), Ibrahim Odwan, Waleed Ahmad, Amera Al-Hemsy, Ali Sawalmeh, Khalil Konsul (President of JAS), Ahmad Naimat, Yahya Bani Hamad, Ghazaleh Al-Abd
Dr. Monzur Ahmed added later:
"The picture of the waning crescent 14th May 1999,
04:20 seems to have been printed back to front or inverted by the telescope.
If this is the case please make this clear on your web page. The
configuration looks like a waxing crescent. I attach a gif (wanecres.gif)
showing a MoonCalc simulation of the same crescent from Amman."
Actually yeah, he is totally right, the picture is rotated by the reflector telescope we used !
So far, the earliest sighting of the crescent was on Sunday 16 May from Iran. The crescent was also seen from Iraq, Jordan, South Africa, Nigeria, Morocco, and Canada.
Sunday 16 May
ICOP member, Mr. Moh'd Murad who was with the other group sent the following report:
"About Nine members of JAS & ICOP joined the observation of Safar 1420 AH crescent, we went to a place near the Eighth Circle in Amman called Abu As-Soos, and we took a telescope and observed the crescent without binoculars. But we had some problems, one of them was that we didn't have the coordinates of the crescent, but we used the coordinates of the pervious day and made some calculations to know the exact ones.
So we tried to see the crescent, and after a while Mr. Marwan Al-Shwaiki told us where we can find the crescent, and said: You can find it here. (and pointed to a direction) and suddenly shouted... Here it is !!! It was in the same direction he pointed at. Unbelievable thing !!
It was 18:41 (Jordanian Local Time) and we were very happy, all of us saw it by naked eyes, and after one minute we all saw it by the telescope.
The crescent was really fantastic, and the observers were: Mohammed Murad (ICOP), Ahmed Al-Naimat (ICOP), Marwan Al-Shwaiki, Basma Diab, Khalil
Konsul (President of JAS), Sydqi Arsan, Amal Al-Ghalaieni, Raid Al-Mughrabi, Arwa Yonus."
