Satellites visible from Madurai (9.9252°N, 78.1198°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.
Madurai lies at about 134 m on the Vaigai plain, the river cutting the city in two, with the Nagamalai and Sirumalai hills on the west and north. Granite outcrops such as Yanaimalai and the rock at Thiruparankundram rise close to town and are the highest vantage points nearby.
Madurai gets only about 670 mm a year, most of it from the north-east monsoon, and October is the wettest month. January to March are the clearest, with almost no rain at all.
Kodaikanal, about 115 km north-west up the ghat road, sits above 2,000 m; its solar observatory, founded in 1899, is where the Evershed effect was discovered.
Madurai has no planetarium, and the Tamil Nadu Astronomy Science Society has asked for one; the nearest is the Birla Planetarium in Chennai.
Pass times for Tiruchirappalli, Tirunelveli.
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.
