small things amuse small minds - ihad a ball getting the ISS crossing the moon

there was a predicted transit of the moon by the ISS for the 27 September 2014 at exactly 19h00m39.26s by CalSky.
I haven't done anything since pulling down the dome back in July. so after realising that the centre line of the event was not far from me (within 9km). so i set off quickly with the canon60D, the polarie head and my slik tripod to a remote section of road at Black Hill. i only had my 200mm lens - the rest of the astro gear is packed up and stored. anyway its nothing special


Crosses the disk of Moon. Separation=0.245° Position Angle=323.9°, Position angle vertex=203.1°. Transit duration=0.44s
Angular diameter=25.2" size=109.0m x 73.0m x 27.5m
Satellite at Azimuth=267.0° W Altitude= 18.4° Distance=1097.1 km Magnitude=0.1mag
In a clock-face concept, the satellite will seem to move toward 2:14
Angular Velocity=18.4'/s

Centerline, closest point →Map: Longitude=151°36'59"E Latitude=-32°50'23" (WGS84) Distance=9.63 km Azimuth=321.5° NW Path direction= 50.3° NE ground speed=9.181 km/s width=12.6 km max. duration=1.6 s
Sun elevation=-15° Elongation from Sun=36°
Orbit source: NASA predicted orbit
