a new outburst of GRO J0422+32
- subject: a new outburst of GRO J0422+32
The V-band CCD observatiosn at Ouda (Nara, Japan; Kyoto Univerisity)
indicates that a new outburst of GRO J0422+32 seems to be in
progress.

On Jan. 7, 1994, the object looks siginificantly brighter. A quick look
of images on the TV monitor shows that the object is presently at
about V=17.5.
This event may provide one of the rare chances to follow the full, esp.
the very initial, course of optical outbursts of USXTs.
Further multiwavelength observations are strongly encouraged.
