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 15 February 2010 and in the Western Region will be on Monday 15 February 2010. 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.





Rabee' Al-Awwal Waxing (NEW) Crescent Observation Results




Sun 14 February 2010



Germany


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 superb, 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 hiked up a 1700m mountain through the snow to get above the cloud layer, which topped at about 1650m. Conditions up there were excellent and the view of isolated peaks sticking out of the clouds was breathtaking. I lugged two telescopes up that mountain: one for visual observation (80mm diameter refractor, 20x or 40x) and a second one (70mm refractor, focal length 400m) with a b/w video-camera attached, also a power-supply and notebook to drive the camera. Both scopes were precisely aligned to show the same field of view. I hoped to use the camera to find the crescent and then have a chance of seeing it visually, too.

Venus was found immediately after sunset, Jupiter too. 
Moving the scope from venus towards the crescent was simple and soon the camera view showed the crescent, exactly as expected: A nice horizontal arc, some 14 hours after conjunction at an elongation of 6.5°. So far, so good.

Alas, despite trying for another 30 minutes until the crescent set, i could NOT see the crescent visually with the 80mm telescope (at 20x or 40x), despite looking at the correct spot, as proven by the live-image. Focus might have been slightly off and i probably also misjudged the size of the crescent i was looking for in the field of view.

So, any visual observation at these elongations obviously is EXTREMELY difficult and will require the very best conditions, optimized equipment and thorough preparation.

Still, a great experience all around.
