2012年2月20日月掩配女星(白天我国不可见,西部为晨光,月亮位于太阳的右上角)Occultation of Eurynome
http://asa.hmnao.com/SecA/2012/occns/occn.2012Feb20.Eurynome.pngThe globe of the Earth is centered on the location at the time of conjunction, and shows the footprint of the shadow at intervals on either side of conjunction.The interval depends on the length of the occultation, with lighter footprints at the start. The first and last footprints are offset by 1s and are drawn in red, which shows where on the Earth the occultation begins and ends.Note these first and last red footprints are very small.
