Observations and data reduction

A new extremely metal-poor BCG, HS 0822+3542, was discovered on April 5, 1998, during observations with the 6m telescope of the Special Astrophysical Observatory (SAO) of the Russian Academy of Sciences (Pustilnik et al. [1999b]), in the framework of the Hamburg/SAO survey for emission-line galaxies (Ugryumov et al. [1999]). Its J2000 coordinates are: R.A. = 08$^{\rm h}$25$^{\rm m}$550, Dec. = +35$^{\circ}$3231. The main parameters of the galaxy are presented in Table 1. Here we present new optical spectroscopic and photometric, and H I 21 cm radio observations to study the properties of this galaxy.
