When to Observe Rabee' Al-Aakher Waxing (NEW) Crescent ?
The geocentric conjunction (Geocentric New Moon) will occur Inshalla on (Sunday 10 February 2013) at 07:20 UT.
Sighting the new crescent on (Sunday 10 February 2013) and (Monday 11 February 2013) is shown in the below graphs using the program Accurate Times by Mohammad Odeh according to Odeh criterion. Where:-
- It is impossible to see the crescent from the areas located under the red color. Because either the Moon on this day sets before the Sunset and/or the topocentric conjunction occurs after the Sunset.
- The crescent is expected to be seen by optical aid only from the areas located under the blue color.
- The crescent is expected to be seen by optical aid from the areas located under the magenta color. In these areas the crescent could be seen by naked eye if the atmospheric conditions are superb and the observer is experienced.
- The crescent is expected to be easily visible by naked eye from the areas located under the green color.
- The crescent cannot be seen from uncolored areas, even though the Moon sets in these locations after the Sunset and the topocentric conjunction occurs before the Sunset, but the Moon is not sufficiently illuminated in order to be seen as crescent even by optical aid.
- Kindly notice that the below graph shows the possibility of seeing the crescent from areas between 60 degrees north of Equator down to 60 degrees south of Equator.
According to the Universal Hejric Calendar (UHC), which is based on the calculated crescent visibility, the start of this month in the Eastern Region will be on Monday 11 February 2013 and in the Western Region will be on Monday 11 February 2013. Kindly notice that the UHC is a pre-calculated calendar, which adopts a certain criterion to start the new Hejric month. Your country/organization might adopt different criterion to start the new Hejric month. So it is highly advised to read the UHC website before giving any judgment.
- Results of seeing the crescent, and the first day of the month in different countries will be added here Inshalla 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.

1 . Time of observation: After sunset.Photographed: ICOP member Eng. Martin Elsaesser from Munich City in Bavaria State mentioned that the sky was clear, the atmospheric condition was clear, the crescent was not sought by naked eye, the crescent was not seen by binocular, the crescent was not sought by telescope, the crescent was seen by CCD Imaging
Eng. Martin Elsaesser said: " The weather was fine with blue skies throughout the day, but the temperature was below zero with some snow on the ground. I had planned to drive to the mountains but the cold and travel problems made me stay in town. I did a daytime observation from home around noon and could image the crescent around 12:30 local time at an elongation 0f 4.7°. For observing after sunset i took my instruments to the public observatory munich and setup on the roof. I could easily find the crescent one hour before sunset with the imaging system at 6° elongation and tracked it until it vanished in a low cloud layer about 15 minutes AFTER sunset. While the imaging system worked by itself i tried to visually find the crescent with 12x50 binoculars of good quality but did not succeed. I should have used a dedicated instrument with higher magnification and tracking for the visual attempt."
