Jumadal Thani Waxing (NEW) Crescent Observation Results

So far, the earliest sighting of the crescent was on Monday 26 June 2006 by Mohammad Odeh from UAE, the crescent was also seen on that day from Iran, Iraq, Senegal, Germany and USA.

Sunday 25 June 2006:

  • USA: ICOP member Dr. John Caldwell said: "Banded and mottled in bottom 5 degrees ; my focus may have been slightly off too although pointing was verified as excellent using Pollux ; not a good test of how visible it would be in good conditions ; useful to fix up my methods though." Dr. Caldwell added that he didn't see the crescent by 20X80 binoculars.

Monday 26 June 2006:

  • Indonesia: ICOP member, Mr. Mutoha MMC said: "Still in my sorrowful of earthquake disaster in my place Yogyakarta (Jogja) on last Saturday 27 May 2006, this day (Monday) 26 June 2006, I have tried to sight the crescent from Parangkusumo Beach of Bantul, Yogyakarta with Brother Agus Triawan the member of JAC. The western sky was clear so only little clouds. Also, I tried locate the position and path of the crescent according to the positions of sunset. Although crescent sets after 37 min of sunset, however I could not see it neither by naked eye, binocular nor my video camera. But Civil Calendar of Islam in Indonesia for first day of Jumadal Akhir determining on Tuesday, 27 June 2006 used "imkan rukyat" criterion.

  • Brunei Darussalam: ICOP member, Mr. Hazarry Haji Ali Ahmad said: "The new moon sighting was held at Shahbandar hill by the Astronomy Unit Personnel, Survey Department. The western horizon was totally cloudy and attempted observation till moonset but new moon was not observed."

  • UAE: ICOP member Mohammad Odeh said:
    Finally after three years of  successive negative observations I was able 
    to see a young crescent! Actually this is the first young crescent I've seen 
    since I left Jordan! In Greece I made several attempts (maybe three or four) 
    and I was not able to see the crescent in any of those! Either it was partly 
    cloudy or hazy or I was not look at the correct location of the crescent, 
    especially that I was using binoculars only! After moving to UAE, I did many 
    serious attempts! Maybe more than six trails! All of which had  failed! And 
    there is a reason for each! Several of them I reached the location of observation 
    late! Where I was trying to observe the crescent from Hafit mountain which is more 
    than 1000m above mean sea-level, and it is about 160 km away from Abu-Dhabi where 
    I live, specifically in Al-Ain city! Actually I don't like to observe from Abu-Dhabi 
    near the sea and at the sea-level! Other attempts were failure because the telescope 
    I borrowed didn't work! I borrowed more than 4 different telescopes, and each has 
    its own problem! When there is no problem in the telescope it was partly cloudy! 
    So imagine my feeling after traveling about 90 minutes to see the crescent and 
    my trial was a failure one! Recently I started to become really nervous after 
    the negative observation! Thus this time I decided not to travel from my city 
    and to observe the crescent from where I live! From Abu-Dhabi! And from the 
    sea-level! Or actually from the sea shore, which is basically the worst location 
    to observe the crescent from! Also I didn't borrow any telescope! I used my 7X50 
    binoculars! Surprisingly I DID see the crescent :-)! Actually the sky was 
    extremely clear compared to the usual atmospheric conditions in Abu-Dhabi! 
    Usually I used to describe these atmospheric conditions as hazy and not 
    that favorable when I was in Jordan!! I was able to see the Sun's limb by 
    naked eyes nearly up to the sunset time, actually at the last few seconds 
    I had to use the binoculars to trace the Sun! Where it disappeared below the sea 
    at 19:14:50 (UT+4), the calculated sunset from my location (taking into account 
    the correct temperature and pressure and the exact coordinates) is 19:50:59! So close! 
    After that I waited for about 5 minutes and then started searching for the crescent, 
    until I couldn't believe when I see it at 19:38!! This is the first young crescent 
    (its age is less than 24 hours) I see after Rajab 1424 AH crescent  ( 28-08-2003)!! 
    I took some photos by my camera, but I think it needs special processing in order 
    to see the crescent, I'll publish them if I succeed in processing them. I can highly 
    claim that I saw the crescent by naked eyes, but can't confirm it. My wife was observing 
    by naked eyes and she also can't confirm whether she saw the crescent or not. Below
