     B. A. Harmon, W. S. Paciesas, and G. J. Fishman, Marshall
Space Flight Center, NASA, report for the Compton Observatory BATSE
Team:  "The radio-jet transient GRO J1655-40, which has been
outburst since late July (IAUC 6196, 6201), reached a peak
intensity in the band 20-100 keV of 650 +/- 30 mCrab on Aug. 1,
decreasing to 80 +/- 20 mCrab as of Aug. 9."
     H. Inoue, F. Nagase, and Y. Ueda, on behalf of the ASCA team,
communicate:  "ASCA will observe this source during Aug. 15.45-
16.18 UT, to investigate jet activity.  Simultaneous optical and
radio observations are encouraged."

     K. Suzuki, Kozakai Senior High School, Aichi, Japan, reports
that an outburst of Perseid meteors was detected by monitoring
forward-scattered meteor echoes via the MU radar wave of Kyoto
University (46.5 MHz, 1 MW) at Toyokawa Meteor Observatory in Aichi.
The maximum hourly rate of echoes reached 300 during Aug. 12.71-
12.79 UT, corresponding to a solar longitude of 139.6 deg (equinox
2000.0).  The hourly rate of long-period (> 5 s) echoes increased
to 5-8 times the usual rate.

     D. George, Kanata, ON, provides the following total magnitude
estimate from an apparent image of the comet on a prediscovery
photograph taken by T. Dickinson (observing in the Chiricahua
Mountains, AZ; 85-mm f/1.7 lens, Kodak Royal Gold 400 film):  May
29.40 UT, 11.7.

     Further to the item on IAUC 6204, T. Dobbins and S. J. O'Meara
report that a photograph taken with the Lick Observatory 0.91-m
refractor on Aug. 12 UT, some 13 hr after ring-plane passage and
using an occulting disk to mask the planet's glare, shows ring
material (possibly due to ring E) out to 2.9 Saturn radii on the
preceding side only.  The first white spot noted on IAUC 6204 had
lost contrast (and dimmed) by Aug. 13 UT, and it had drifted to
longitude 359 deg (system I).

1995 August 14                 (6205)            Daniel W. E. Green
