Satellites visible from Bhagalpur (25.2425°N, 86.9842°E) tonight, with the IST start time, direction, peak height and brightness of each pass. A pass is listed only when the satellite clears 10°, is sunlit, your sky is dark and it reaches about magnitude 4.5.
Bhagalpur lies on the south bank of the Ganga in eastern Bihar, about 190 km east of Patna. The river runs along the city's northern edge, so facing north across the water gives the widest, darkest horizon in town.
The monsoon reaches eastern Bihar in mid-June and lasts into early October. Fog settles over the Ganga plain in December and January, which makes October, November and March the most reliable months.
The Vikramshila Gangetic Dolphin Sanctuary, the stretch of the Ganga between Sultanganj and Kahalgaon, has very few lights along its banks.
Pass times for Purnia, Darbhanga.
The ISS is the brightest at magnitude -3 to -4, followed by China's Tiangong station, large Earth-observation satellites, spent rocket bodies and Starlink trains in the days after a launch. GPS and NavIC satellites orbit too high to see with the naked eye.
