Time (24-hour clock) Object (Link) Event
15h19m49.74s
ISS
Crosses the disk of Sun. Separation=0.228° Position Angle=9.7°, Position angle vertex=347.3°. Transit duration=0.71s
Angular diameter=28.4" size=109.0m x 73.0m x 27.5m
Satellite at Azimuth=224.1° SW Altitude= 19.5° Distance=972.2 km
In a clock-face concept, the satellite will seem to move toward 9:25
Angular Velocity=24.0'/s
Centerline, closest point →Map: Longitude= 24°07'41"E Latitude=+57°02'17" (WGS84) Distance=9.92 km Azimuth= 9.8° N Path direction= 99.7° E ground speed=8.100 km/s width=12.5 km max. duration=1.4 s

ISS Double Solar Transit
ISS crosses the disk of Sun twice seen from the same geographical position at
→Map WGS84: lon=26.310693° lat=57.145082°
First crossing occurs at list time, the second transit 1 orbit(s) later.
(135 km from selected site)
