GRO J0422+32
     N. Shakhovskoj, Crimean Astrophysical Observatory, reports the
following position obtained with the 1.25-m reflector:  R.A. =
4h18m35s.3, Decl. = +32 47'29" (equinox 1950.0).  Shakhovskoj also
provides the following photometry:  Aug. 16.04 UT, U = 13.07, B =
13.52, V = 13.21, R = 12.77, I = 12.32; Aug. 17.00, 13.13, 13.52,
13.30, 12.85, 12.54.


GRS 1915+105
     A. J. Castro-Tirado, S. Brandt, and N. Lund, Granat WATCH team
(Danish Space Research Institute, Lyngby; and Space Research
Institute, Moscow), report:  "A new x-ray transient in Aquila has been
discovered in data obtained by the WATCH all-sky monitor on Granat
on Aug. 15.  The source strength is about 300 mCrab.  The source
has been localized to the following position:  R.A. = 19h14m.9,
Decl. = +10 28' (equinox 1950.0), with a probable error radius 0.5
deg.  Follow-up observations are encouraged."
