Satellites visible from Ludhiana (30.9010°N, 75.8573°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.
Ludhiana stands at about 244 m on an old bank of the Sutlej, whose present course runs some 13 km north of the city. It sits in the middle of Punjab's paddy belt, and the fire counts that track crop-residue burning across the state are compiled by the Punjab Remote Sensing Centre here.
July and August are the wettest months. In late October and November stubble smoke can push the AQI above 400, and December lows near 7 °C bring fog, so February and March are the dependable months.
No verified dark site is close; the farmland along the Sutlej north of the city is the nearest open, lightly lit ground.
The municipal Nehru Planetarium in the Rose Garden has long needed an upgrade, so check before visiting. Pushpa Gujral Science City near Kapurthala has a 23 m dome with 328 seats.
Pass times for Jalandhar, Patiala, Mohali.
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.
