إمكانية رؤية الهلال يوم السبت 21 نيسان / إبريل 2012 ويوم الأحد 22 نيسان / إبريل 2012 موضحة في الأشكال التالية باستخدام برنامج المواقيت الدقيقة باعتماد معيار عودة، بحيث:-
باعتماد التقويم الهجري العالمي المبني على حساب إمكانية رؤية الهلال، فإن بداية الشهر في النطاق الشرقي تكون يوم الاثنين 23 نيسان / إبريل 2012 ، وبداية الشهر في النطاق الغربي تكون يوم الأحد 22 نيسان / إبريل 2012 . الرجاء ملاحظة أن التقويم الهجري العالمي يعتمد على الحسابات المسبقة ( اي لا ينتظر الرصد العملي و رؤية الهلال ) و هو يتبنى معياراً معينا لبدء الشهر الهجري الجديد .و قد تتبنى بلدك او منظمتك معياراً آخر لبدء الشهر لذا فإننا ننصح و بشدة أن يتم الاطلاع عما جاء في صفحة التقويم الهجري العالمي في موقعنا قبل إصدار اي أحكام .
ستضاف نتائج تحري الهلال وبداية الشهر الرسمية في مختلف الدول الإسلامية في هذه الصفحة إن شاء الله فور استلام نتائج الرصد من قبل أعضاء المشروع الإسلامي لرصد الأهلة.
وقال عضو المشروع المهندس مارتن إليسياسر "The young crescent of 21. April was very difficult, as conjunction was very close at only 2.2° elongation. We had good clear skies before noon, but did not attempt to see the crescent due to the extreme closeness to the sun. Around noon, the skies started to get more cloudy, with layers of high altitude haze, so we did not expect any chance to observe in the evening. The clarity of the air was excellent though, due to the wind and dry air. Unexpectedly, around 17:00 a huge gap in the clouds started to form from a local weather phenomenon called the "Föhn", so i hurriedly set up a crescent imaging telescope at the public astronomical observatory in the center of munich, not having the time to go to a better location. I also asked two visitors from Oman to join me, as we had been testing the crescent telescope for a few days. After setup of the instrument on a neighboring roof we aligned the goto-system on the sun, adjusted focus by looking at jupiter and then sent the goto system to the position of the moon. We moved the instrument slighly downwards, to get the actual crescent into the center of the field of view. We used the prototype of a spezialized software to automatically adjust camera settings and do the real time image processing, so we mainly stood around without much to do, staring on the screen to look for the crescent. We could not clearly see the crescent on the screen, but a quick review of the automatically saved images showed a thin arc of light moving among the haze and noise, so we rejoiced. Alas, it quickly became clear that the gap in the clouds was only temporary and that we would not be able to observe until sunset. We first found the crescent around 19:05 (UT+2), at an elongation of 4.23°, an altitude of 14°, about 75 minutes before sunset. We lost it to the fast-moving clouds around 15 minutes later, about one hour before sunset. When inspecting the captured images later, i found no single good, convincing image. So i cut about 60 images from the stream and combined them to a short video, which clearly shows the moving arc. The short video can be found on my homepage: http://www.mondatlas.de/other/martinel/sicheln2012/april/index.html So, a nice, if short observation of the crescent at very small elongations. Sadly, the clouds prevented us from following the crescent till after sunset and we also could not try visual observation, though the telescope would have been ready for it. The special software worked fine, but needs a few more tweaks."
وقال عضو المشروع المهندس قمر الدين "On Saturday, 21 April 2012 (29 Jumada al-Ula 1433 AH) many people from throughout UK have attempted to sight the crescent moon (Hilal) of Jumada Al-Ukhra after sunset. None of the groups were able to sight the Hilal, as most places were cloudy/rainy. We have not received any reliable sighting reports (Muhaqaq-Ruyat-Basari) from any countries east of UK/Morocco either. But, we have received a negative sighting report from Morocco Awqaf Ministry. Therefore, the Wifaq/Batley Ulama have decided that the month of Jumada al-Ula 1433 AH will completed 30 days and the month of Jumada Al-Ukhra 1433 AH will start from Monday 23 April 2012 (i.e. sunset of 22 April 2012), Insha-Allah."
وقال عضو المشروع السيد جيم ستام "New Moon Crescent Observation Report ====================================== Observed: Saturday; April 21, 2012 - 19:14 (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 = 30 °C Humidity = 10 % Pressure = 29.73 in. Only very slight haze kept the sky from being perfect. Magnitude limit at 4 degrees altitude with 80 power in C-8 telescope, after onset of twilight was 9.5, and this wavered to much less at times. It appears that this magnitude measurement is not a good indication of the sky’s transparency for evening, new moon crescent observations. Topocentric and local time values from “Accurate Times”: Sunset (at sea level) = 19:03 Moonset (at sea level) = 19:44 Time from new moon at 19:14 = 18 hr. 34 min. Moon lag time = 41 min. Relative Altitude = 7.9 degrees Elongation from sun = 7.9 degrees Crescent width = 9 arc seconds Illumination = 0.5 percent Crescent first observed through 8” SC telescope: Time = 19:14 Moon Altitude = 3.9 degrees Final observation with telescope: Time = 19:27 Moon Altitude = 1.4 degrees The crescent was easily seen entering the eyepiece field at 19:14. It extended from about 20 arc degrees to about 50 degrees in several seconds, then to 70 degrees in a minute. It dropped back to about 60 degrees, and stayed like that for about 8 or 9 minutes. Then it quickly lessened to about 30 degrees, until I lost it in the trees at 19:27. There were several degrees of the arc that stayed invisible, leaving about twice as much arc separated from the rest of the crescent. None of my photographs (zoomed, but not using the telescope optics) picked up the crescent. Observers: Jim and Chris Stamm E-mail Address: StammJim@gmail.com"
وقال عضو المشروع السيد حسين الشيخ عيسى "(25) persons were present in n'tissa station and have tried to observe the Jumada II 1433 crescent. the crescent was seen. They have used three binoculars : 60x20, 50x07 and 50x08 and telescop."
وقال عضو المشروع المهندس مارتن إليسياسر "The day started rainy, but got better in the afternoon. Between the clouds, the air was very clear. The crescent could first be seen around 18:40 (UT+2), some 90 minutes before sunset, using a small telescope at 50x. The sky was good blue and the crescent appeared as a whiter arc, even showing some structure. Jupiter could also be seen and even showed cloudbelts at that time. After sunset, the crescent could easily be seen with the naked eye, with jupiter 2 degrees to the left."
وقال عضو المشروع السيد صالح الصعب "The atmosphere was very dusty, the sun disappeared 30 minutes before sunset."
وقال عضو المشروع الدكتور جواد تورابنيجاد "My son and I arrived at our sighting location at 7:58 pm EDT (sunset: 8:03 pm). The sky was cloudy. We stayed there till 8:13 pm (moonset: 9:36 pm)."

وقال عضو المشروع السيد علام سلطان "Alhamdolillah, today (Sunday 22 April 2012= 29 Jumadal-oola 1433 in Pakistan), On my request, a large number of people (members of the moon-sighting committees of our institute "JAMIA-TUR-RASHEED" + my friends + their companions) easily sighted the moon at 16 places in all 4 provinces. Due to haze, some clouds and low phase of moon(less than 2%) I could not sight it myself in Karachi. Note 1: Chairman of central official moon sighting committee of Pakistan mufti munee-bur-Rahman told me on my mobile phone that as he also received positive reports therefore he announced officially that Monday 23 April 2012 is 1st Juma-dath-Thaniah 1433 in Pakistan. Jumadal-oola month finished on 29th day. Note2 : After some days, inshaallah, a detailed report of this observation in Urdu will be available. "
وقال عضو المشروع السيد ظفار شريف "The crescent was easily sighted."
وقال عضو المشروع الدكتور عبد العزيز إبراهيم "The Hilaal was not seen in Cape Town but it was seen by naked-eye in the northern South African areas of Rustenburg and Johannesburg."
وقال عضو المشروع السيد قاسم بهالي "The hilal was seen at Al-Khawarizmi Observatory with Meade LX200 8" and naked eyes."
وقال عضو المشروع السيد فردوس مزلان "On Sunday, 22th April 2012 M equal to 29th Jumada-al-Oola 1433 H, I with my friend (Mr. Mohammad Haniff bin Md Yusoff, Mr. Muhammad Zainal Abiden bin Mohamad Hani, Mr. Asmanizam bin Ghani, Mr. Mohd Fahmi bin Zakaria, Mr. Abdul Hai Amri bin Alias, Mr. Mohd Fairuz, Mr. Nadzrin) have seen the new moon with naked eye at Baitul Hilal, Teluk Kemang, Negeri Sembilan, Malaysia (02:26:43.0 N , 101:51:16.0 E). The crescent was first seen by Telescope at 7.38 pm. After that, we can see the crescent at 7.46 pm until 7.55 pm. So, tomorrow, 23th April 2012 M (Monday) is 1st Jumada-al-Thani 1433 H. The goverment also announced that tomorrow is 1st Jumada-al-Thani 1433 H. "
وقال عضو المشروع السيد قمر الدين محمد "I couldn't sight the new hilal tonight"

The sky seemed to be more clear than last month, and I speculate that either 31% humidity is too much, or the crescent’s altitude lessened its contrast, thus making it invisible.
