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
