Calsky says there is an ISS pass at 9h23m24.30s this Friday.
The ideal location is around Fairfield showground (market).
That's a new moon at about 20 deg up, 15deg from the sun.
Curious if anything would show up on camera.
Would you pick up the ISS as a dark dot outside the moon disc?
Has anyone tried a pass in daylight?
Details as follow:
Crosses the disk of Moon. Separation=0.192° Position Angle=32.8°, Position angle vertex=154.1°. Transit duration=1.04s
Angular diameter=25.9" size=109.0m x 73.0m x 27.5m
Satellite at Azimuth= 95.8° E Altitude= 18.7° Distance=1068.5 km Magnitude=1.1mag
In a clock-face concept, the satellite will seem to move toward 3:52
Angular Velocity=18.1'/s
Centerline, closest point →Map: Longitude=150°54'19"E Latitude=-33°52'06" (WGS84) Distance=6.84 km Azimuth= 39.6° NE Path direction=129.4° SE ground speed=9.279 km/s width=11.9 km max. duration=1.6 s
Sun altitude=+39° Elongation from Sun=20°
