Alhamdulillah the Islamic Circle of North America (ICNA) has also endorsed the decision of Hilal Sighting Committee of North America and announced Eid Ul Adha for Tuesday, December 9 Insha’Allaah.
Extending our Matla to South America could present major problems such as asking New York to start/stop fasting due to Hilal sighting e.g. in Argentina, even when New York Moonset is BEFORE Sunset! Seasons (Summer / Winters) have major effect on Hilal visibility curves (roughly parabola shaped) and the seasons reverse when you go to South America. Futher, in Hadith Kurayb, Damascas sighting is not accepted for Medinah Munawwarah even though most of the distance between Damascus and Medina is North – South. Thus Insha’Allaah we should in fact contemplate reducing our Matla and at the very least not increasing it.
