G. Maheswar and H. C. Bhatt, Indian Institute of Astrophysics, Bangalore, report on observations of the optical nebula associated with IRAS 05436-0007 (cf. IAUC 8284) made at the Kavalur Observatory 2.3-m Vainu Bappu Telescope (VBT) and the Hanle Observatory 2-m Himalayan Chandra Telescope (HCT). VBT R-band CCD imaging on Feb. 19.7 UT yields magnitudes 16.8 in a 6" aperture and 13.6 in an 80" aperture. HCT CCD imaging on Feb. 22.7 gave V = 18.1, R = 16.5, and I = 14.5 in a 6" aperture, and V = 14.0, R = 13.2, and I = 12.1 in an 80" aperture. An optical spectrum (resolution of 0.12 nm/pixel) with the HCT (+ HFOSC) on Feb. 23.7 shows H_alpha and near-infrared Ca II triplet lines in emission. H_alpha shows a P-Cyg profile with an eqivalent width of the emission component of 3.2 nm, the absorption component having a peak at a velocity of 460 km/s. The O I line at 777.3 nm is seen in absorption with an equivalent width of 0.24 nm.
