Abstract: Ground-based measurements of OH (8, 3) Meinel band emissions were carried out at Kolhapur (16.8ºN, 74.1ºE), India during November 2002 – May 2003 using two tilting filter photometers. OH rotational temperature ~ a proxy of atmospheric temperature around 87 km, were derived from the intensity information of P1(2) and P1(4) lines of OH (8, 3) band. On most nights, strong well-defined oscillations having periodicities in the range of 1 – 3 h were observed in OH temperature series. In this paper, a case study of such short-period oscillations, observed on few nights in the OH temperature, has been presented.
