Reappearance of 22 GHz water maser in proto-planetary nebula OH17.7-2.0.
Abstract
We observed OH17.7-2.0 (also known as: IRAS18276-1431, V445 Sct), a young proto-planetary nebula (Sanchez Contreras et al., 2007, ApJ, 656, 1150; Bains et al., 2003, MNRAS, 338, 287), in the 22 GHz water maser line using a new K-band receiver at the Torun 32m radio telescope. The system equivalent flux density was about 480 Jy and spectral resolution was 0.03 km/s.
