Abstract:
A group of five observers have participated in visual, photographic and MST radar observations of Leonid meteor shower during 15-20 November 1998 at National MST Radar Facility (NMRF), Gadanki (13.47 deg N, 79.18 deg E) near Tirupati. The peak activity of the shower occurred at 00:00 hours UT on 17 November with a maximum rate of 450 per hour in visual and 1250 per hour in radar observations. These rates are very less compared to the rates observed during 1966 return of the shower. Simultaneous observations of Es occurrences during the shower period showed a spread of about 20-30 Km around 90 Km height region. Most of the Leonid meteor radar echoes occurred around 100 km range.
