Jumadal Al-Aakherah Waxing (NEW) Crescent Observation Results




Tue 03 May 2011



Algeria


1 . Time of observation: After sunset. Not Seen: ICOP member Mr. Hocine Chikh Aissa from Ghardaia City in Ghardaia State mentioned that the sky was clear, the atmospheric condition was superb, the crescent was not seen by naked eye, the crescent was not seen by binocular, the crescent was not sought by telescope, the crescent was not sought by CCD Imaging
Mr. Hocine Chikh Aissa said: "(12) persons were present in N'tissa station and have tried to observe the Jumada II 1432 crescent but it wasn't seen. The western horizon was supreb after rain. They have used one binocular : 50x7"



Germany


1 . Time of observation: After sunset. Not Seen: ICOP member Eng. Martin Elsaesser from Munich City in Bavaria State mentioned that the sky was clear, the atmospheric condition was hazy, the crescent was not seen by naked eye, the crescent was not sought by binocular, the crescent was not sought by telescope, the crescent was not seen by CCD Imaging
Eng. Martin Elsaesser said: "I gave it a try with the imaging equipment from a local site, but could only carry a small lens with tripod. Weather conditions were very hazy near the horizon (at only 5°C, clouds from day-long rain just moving away) and i was not sure enough of the position. I tried scanning back and forth across the assumed path of the crescent for 30 minutes but could NOT see the crescent on the screen, nor find it in the saved images later. At only 5.5° of elongation it takes better weather and better preparation."



United Kingdom


1 . Time of observation: After sunset. Not Seen: ICOP member Eng. Qamar Uddin from York City in North Yorkshire State mentioned that the sky was totally cloudy, the atmospheric condition was hazy, the crescent was not seen by naked eye, the crescent was not sought by binocular, the crescent was not sought by telescope, the crescent was not sought by CCD Imaging
Eng. Qamar Uddin said: "On Tuesday 3 May 2011 (29 Jumada Al-Ula 1432 AH) many people from throughout UK have attempted to sight the crescent moon (Hilal) of Jumada Al-Ukhra  (or Jumada Al-Thani) after sunset. None of the groups were able to sight the Hilal, even though some places had clear sky conditions.

We have not received any reliable sighting news from countries east of UK or Morocco either. Fax received from Morocco Awqaf Ministry had negative sighting reports from all 278 points within the entire country. 

Therefore, the Ulama (including Wifaq/Batley) have decided that the month of Jumada Al-Ula 1432 AH will complete 30 days and the month of Jumada Al-Ukhra 1432 AH will start from Thursday 5 May 2011, Insha-Allah."

Dr. John Caldwell said: "43 min lag, some cloud bands but "clear" bands too, surprised not to
see it in binoculars, did not look like so bad conditions, even saw
multiple very distant airplane trails near that horizon"



3 . Time of observation: After sunset. Seen: ICOP member Mr. Jim Stamm from Tucson City in AZ State mentioned that the sky was partly cloudy, the atmospheric condition was clear, the crescent was not sought by naked eye, the crescent was not seen by binocular, the crescent was seen by telescope, the crescent was not sought by CCD Imaging
Mr. Jim Stamm said: "Observed:   Tuesday; May 03, 2011  -  19:18 (Local). Location (WGS 84) = Tucson, Arizona (USA).   Longitude = 110.9651 W.   Latitude  =  32.4206 N.   Elevation = 842 meters.   Time Zone = -7.0 hours. Surface conditions at location:  Temperature =  26 °C.   Humidity    =   5 %.   Pressure    =  29.85 in.A few clouds near the horizon, but none interfering. Topocentric and local time values from “Accurate Times”:    Sunset (at sea level)   =  19:11.   Moonset (at sea level)  =  19:57.  Time from new moon at   19:32   =  19 hr. 13 min.   Moon lag time                   =         46 min.   Relative Altitude               =    8.7  degrees.   Elongation from sun             =    8.7  degrees.   Crescent width                  =     10  arc seconds.
   Illumination                    =    0.6  percent. Crescent first observed through 8” SC telescope:   Time   =   19:18.   Moon Altitude  =    4.1 degrees. Final observation with telescope:   Time   =   19:38.   Moon Altitude  =    1.7 degrees. I pre-aimed the scope the night before.  The crescent was invisible in the eyepiece FOV from 19:14 until 19:18, when it became visible right in the center of the FOV.  The length of the crescent was about 30 degrees initially.  It grew southward to 60 degrees by 19:20, southward to 80 degrees by 19:23, southward to 90 degrees by 19:24, and slowly northward to 100 degrees by 19:28.  For the next ten minutes the length of the arc of the crescent did not seem to grow at all.  I lost the moon in the trees at 19:38.  I tried to view the crescent with two different binoculars and my finder, without success.  I also tried to photograph the crescent by holding a camera at the eyepiece, without success.

Eng. Mohammad Odeh said: "Hidden haze! Yes hidden haze! It was really difficult to imagine how hazy the sky was until the Sun had set, where I was not able to see the crescent by telescope despite the fact that it had to be easily seen by naked eye! The accuracy of the telescope was tested several times by pointing it to Venus and Sirius and they were seen in the field of view! Also, the Sun itself had disappeared well before the actual  sunset time! 22 trials were done by CCD imaging to see the crescent from 10 am till 06 pm. The crescent was barely visible in the 13th trial at 16:35 (LT). The elongation at that time was 13.5 degrees, Moon altitude was 43 degrees, and the Sun altitude was 30 degrees. The crescent was also visible in the 14th trial at 17:00 LT but it was more difficult to be seen than the 13th trial! The last trial in which the crescent was visible was the 15th trial at 17:09! In that trial the crescent was VERY difficult to be seen! All these trials show how critical the haze is on crescent observation! So always do you best to observe from the highest possible altitude to reduce the haze effect! Below are two photos for the crescent for the 13th trial. Kindly notice that it is the same photo with different processing settings."

The western sky was partly cloudy, but we managed to sight the Hilal with 10x50 binoculars at 21:09 hrs BST and by naked eye at 21:14 hrs BST (see attached photo). The Hilal was also live broadcasted on the Internet and partly recorded online (2 mins). Note that the Ulama in UK have already decided yesterday to start Jumada Al-Ukhra 1432 from Thursday 5 May 2011 by completing Jumada Al-Ula as 30-days."

Jumadal Al-Aula Waning (OLD) Crescent Observation Results




Sun 01 May 2011



Germany


1 . Time of observation: Before sunrise. Seen: ICOP member Eng. Martin Elsaesser from Munich City in Bavaria State mentioned that the sky was clear, the atmospheric condition was hazy, the crescent was seen by naked eye, the crescent was seen by binocular, the crescent was not sought by telescope, the crescent was not sought by CCD Imaging
Eng. Martin Elsaesser said: "The crescent was easily seen with the naked eye and small binoculars, after it had risen above some low cloud layer."



United Kingdom


1 . Time of observation: Before sunrise. Not Seen: ICOP member Eng. Qamar Uddin from York City in North Yorkshire State mentioned that the sky was totally cloudy, the atmospheric condition was hazy, the crescent was not seen by naked eye, the crescent was not seen by binocular, the crescent was not sought by telescope, the crescent was not sought by CCD Imaging
Eng. Qamar Uddin said: "The eastern horizon before sunrise was totally cloudy, hence the waning crescent was not seen from York (UK)."



Mon 02 May 2011



Germany


1 . Time of observation: Before sunrise.Photographed: ICOP member Eng. Martin Elsaesser from Munich City in Bavaria State mentioned that the sky was partly cloudy, the atmospheric condition was very hazy, the crescent was not sought by naked eye, the crescent was not sought by binocular, the crescent was not seen by telescope, the crescent was seen by CCD Imaging
Eng. Martin Elsaesser said: "I tried to observe the crescent during morning twilight, but did not succeed due to lots of fog, that went higher than my observation spot, a local sight-seeing tower. The upper-most layer of fog was flowing over me, but that was not good enough to see the thin crescent.

The fog/clouds only resolved after noon, but a lot of haze remained and conditions weree quite bad. I could not see the crescent visually in a small telescope, so i had to resort to the imaging approach. 
Despite a very low contrast of less than 1% brightness increase vs. the surrounding sky and any amount of haze and flying insects and pollen and such, the crescent could be imaged and viewed on the live-screen at about 9.6° elongation from the sun. At the time of observation the old crescent was already descending again in front of the sun."



United Arab Emirates


1 . Time of observation: Before sunrise.Photographed: ICOP member Eng. Mohammad Odeh from Mussafah City in Abu Dhabi State mentioned that the sky was partly cloudy, the atmospheric condition was hazy, the crescent was not sought by naked eye, the crescent was not sought by binocular, the crescent was not seen by telescope, the crescent was seen by CCD Imaging
Eng. Mohammad Odeh said: "Seen by CCD imaging at: 10:26 LT (UT+4). Weather Conditions were not perfect. I'd consider it to be a little bit below the average for this area. Generally speaking, it was well below the good atmospheric conditions!"
