ISS Transit of Sun
ISS transit of Sun, September 2, 2010 5:46:45 CDT
CalSky ISS Transit data at Spot Observatory:
Separation=0.197° Position Angle=267.6°. Transit duration=1.23s
Angular diameter=18.8" size=73.0m x 44.5m x 27.5m
Satellite at Azimuth=267.1° W Altitude= 17.1° Distance=986.3 km
Angular Velocity=17.2'/s
Centerline, closest point Longitude= 87°35'36" W
Latitude=+35°55'41" (WGS84) Distance=5.43 km Azimuth=332.4°
NNW Path direction= 62.4° ENE ground speed=9.929 km/s
width=10.2 km max. duration=1.8 s
AP 1200GTO
AP155EDF with 0.5x focal reducer, EFL=589 mm
Baader solar film full aperture
Lumenera SKYnyx 2-0M
Image scale: 2.6 arc sec per pixel
Capture duration of AVI: approx. 2 sec
Capture frame speed: 52 fps, exposure 0.02 ms
Capture format: Ser / 16Bit.
SER converted to BMP, written to AVI, and then converted and
uploaded as compressed Windows .wmv file.
The Sun at the time of the transit was at 17 degrees altitude, with
passing clouds. To get most of the Sun's disk in the frame, I used a
focal reducer. The short focal length and altitude/clouds resulted in
poor resolution.
