this morning i’m pretty luck. my ipcam (rtsp / cv2) running STVID by @cgbsat captured the ISRO satellites ASTROSAT (norad id 40930) over my station on Indonesia (UTC+8). what special from this satellites are, these satellite have very low inclination around 6 degree, orbiting earth equator, and same launch with IO86 (40931)
observation date/time: 2026-09-22T21:12:12 UTC

what we know about this satellite:
almost 1.5 ton. thats heavy satellite 
comparing with io86 that just only 76 kg (microsat)
and using the stellarium, i know the magnitude when this satellite pass my station :
Approx. magnitude: 7.27
and using gpredict i know exactly the azimuth and elevation based on TLE
and to make it more fun, i paste the iod result on my newest playground, iod tracker
first i set my location settings, and paste the iod.
i also paste the current TLE of astrosat, just to make comparation about my optical observation vs the spacetrack TLE
