At 2025-09-07 18:49:47.280UT, while monitoring the impact of meteorites during the total lunar eclipse, we clearly observed a signature of impact, creating two bright regions near Mare Tranquilltatis. Fig. 1 (http://csp.res.in/images/fig1.jpg) shows our observed frame. Fig. 2 (http://csp.res.in/images/fig2.jpg) shows the subtracted from the earlier frame taken 3s prior to this. Fig. 3 (http://csp.res.in/images/fig3.jpg) shows approximate locations of the event. We used 10 inch Meade reflector located at IERCOO, Sitapur (87.79E, 22.51N) with an ATIK camera (1391x1039) and an exposure of 1s.
The simultaneous impacts indicate a possible grazing incidence of a meteorite with a valley on its path. Size of each pixel is about 2.4km which limits the width of possible craters. We encourage LRO
to observe formations of possible new craters in these locations. We encourage other observers to check if any event was seen in other wavelengths.
