Аннотация:The X-ray Nova GRO JO422+32 in its low brightness has been identified with a faint star on both blue and red Palomar Sky Survey glass copies (see Figures 1 and 2). The scans obtained with an automatic microdensitometer were processed with our special PC program to strengthen the contrast of the image. The magnitudes measured are the following: B = 20.9 ± O.3 mag; R = 20.1 ± O.5 mag. The resulting outburst amplitude 7.7 ± O.6 mag is one of similarity features for the class of the low mass X-ray Novae black hole candidates.
