Jordan Astronomical Society confirms sighting of Ramadan crescent on Tuesday 17 February impossible by naked eye, telescope or astrophotography in Jordan and surrounding regions, indicating first day of Ramadan on 19 February.
Society Director General Ammar Al-Sakaji says astronomical data for Ramadan 1447 AH central conjunction at 15:03 and apparent conjunction at 16:47 Jordan time on 17 February. Moon sets about 3 minutes after sunset, moon age about 3 hours 21 minutes centrally and about 1.5 hours apparently, altitude difference 14 arcminutes, angular separation 1 degree 14 arcminutes, illumination not exceeding 0.01%, with crescent thickness practically zero.
Based on these parameters, all below Danjon limit, crescent sighting impossible in Jordan and nearby and distant regions.
Al-Sakaji adds that all old and modern crescent visibility criteria, including Babylonian, Indian, Bruin, Fotheringham, Maunder, Ibn Tariq, Ilyas, Alawi, Yallop, South African Observatory and Odeh criteria adopted by society, confirm impossibility of sighting on that day across Arab and Islamic worlds.
He notes an annular/partial solar eclipse will occur on Tuesday 17 February at 12:56 Jordan time, not visible from Jordan. Eclipse coincides with sunset across eastern and central world to western Asia, serving as clear evidence crescent cannot be seen during or shortly after eclipse.
Visibility maps based on Odeh criterion crescent sighting on 17–18 February impossible in red zones, not possible by telescope or naked eye in uncoloured zones, possible only by telescope in blue and pink zones, and by naked eye only in green zones under perfect atmospheric conditions by experienced observers.
