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.

Syntax of coordinates is : "ra dec (wtype) [error ellipse] quality bibcode" :
ra dec : right ascension and declination (unit and frame defined according to your Output Options)
Grey values are increasing the original precision due to the computation of frame transformations
(wtype) : wavelength class for the origin of the coordinates (Rad, mm, IR, Optical, UV, Xray, Gam)
[error ellipse] : measurement uncertainty, on (ra,dec) if the positional angle is 90 degrees, on (majaxis,minaxis) otherwise (in mas at defined epoch in the original catalogue),
position angle (in degrees North celestial pole to East)

value : radial velocity or/and redshift (Heliocentric frame) according to your Output Options
(redshift may be not displayed if the data value is <0 and the database inside value is a radial velocity)
[error] : error of the corresponding value displayed before
(wavelength) : wavelength range of the measurement : Rad, mm, IR, Opt, UV, Xray, Gam or '∼'(unknown)
quality : flag of quality ( A=best quality -> E=worst quality, ∼=unknown quality)
