Title: Extended Red Emission in Mahadevpur (Namsai) Meteorite
Author: Dehingia, Nayanjyoti; Baruah, Gaurangadhar

Laser-induced fluorescence spectrum of Mahadevpur (near Namsai) meteorite of type H4/5 ordinary chondrite was excited with the help of a 25-mW green diode-pumped solid-state laser (532 nm), and a diffuse spectrum was photographed on a glass spectrograph in the wavelength range of 5400-6500 A. The band system is attributed to silicate (olivine), a major component of the meteorite. A comparison of the emission system with that of Dergaon meteorite of type H5 ordinary chondrite was made.
