Abstract

Five transitions of CH3OH, corresponding to the J = 4, 5, 6, 7, and 8 rotational levels, at frequencies of approximately 25 GHz, have been detected in Orion A. The source of emission is less than 1 arc minute in angular size and appears to be coincident with the infrared nebula. Although departures from LTE are evident in the line intensities, if the emission originates in the infrared nebula then a temperature of 90� K, a column density of 10^16 CH3OH molecules per cm2, and a CH3OH density of 0.25 molecules per cm3 are indicated. Collisional excitation requires a total gas density of 2 x 10^6 cm-3 and a total mass of gas in excess of 20 M_sol
