GRO J0422+32
P. Zhao, P. Callanan, M. Garcia, and J. McClintock, Smithsonian
Astrophysical Observatory, write: "On Jan. 30.29 UT, the x-ray nova
J0422+32 was fainter than at any time since its outburst in Aug.
1992 (IAUC 5580): R = 20.03 +/- 0.11 and V = 20.67 +/- 0.22, which
is 8 mag fainter than its maximum brightness during outburst (IAUC
5588). These CCD photometric data were obtained with the F. L.
Whipple Observatory's 1.2-m telescope. The magnitudes on two pre-
ceding nights were: Jan. 21.15, R = 18.66 +/- 0.03, V = 19.31 +/-
0.06; 22.15, 19.09 +/- 0.16, 19.83 +/- 0.29. This new faint state
provides the best opportunity to date of measuring the radial velo-
city variations of the secondary star."
