Visual observations of Geminid meteor shower 2004
Abstract
Based on 19 hours of effective visual observations with a group of 5 observers, we detected a total of 2352 Geminid meteors from Japal - Rangapur Observatory, a low latitude station. From three days observations of Geminid meteor shower during 11-14 December, 2004, we observed that the peak activity of the shower occurred at 20:30 hrs UT on 13 December with a maximum rate of 257 meteors per hour. The Geminid meteor shower activity produced more number of faint meteors compared to bright meteors on the peak day. The population index value is also high on the peak day of the activity leading to a conclusion that the shower contains more number of small size particles at the centre of the stream. Here we present an analysis of the activity profile of the shower, the magnitude and directional variation of the shower. The luminosity class distribution of the shower is also presented and discussed.
