The crescent will not be visible anywhere on this day. It can be easily seen on Wednesday, 22 February 2012 in North America.
According to the rulings of Ayatullah Sistani (based on The Theory of Differing Horizons), 1st Rabi’al Thaani 1433AH will be on Thursday, 23 February 2012 or Friday, 24 February 2012. For the Muqallideen of Marhum Ayatullah Khui, 1st Rabi’al Thanni 1433AH will be on Thursday, 23 February 2012.
Please note that in UK, on Wednesday 22nd February 2012, the crescent will InshaaAllah be on the horizon for quite a long time after sunset. Although the moon elongation at sunset will be just outside our community criteria for crescent sighting, it is possible that under perfect conditions, the crescent could be sighted.
The Hilal Advisory Team of The Council of European Jamaats, would like to request those Moamineen who are free on Wednesday 22nd February 2012 after sunset, to go and look for the crescent. Please contact the Secretariat to get the exact timings and crescent position in the sky for your location
