Description

The flare of H2O maser emission in Orion A was observed with the Crimea--Effelsberg and Haystack--Green Bank interferometers in November 1979. Its position is α = 5/sup h/32/sup m/46/sup s/.6 +- 0/sup s/.06, delta = -5024'.28''.7 +- 1'' (1950.0); its radial velocity, 8 km/sec. The asymmetric line profile has a 28-kHz halfwidth. The flare source comprises a 0''.0005 core (T/sub b/ = 5 x 10160K) embedded in a 0''.005 halo (T/sub b/ = 3 x 10140K)
