SUPERNOVA 1988S IN ANONYMOUS GALAXY
C. Pollas, Observatoire de la Cote d'Azur, telexes his discovery
of an apparent supernova located at R.A. = 23h48m25.57, Decl. =
+8 23'47.6 (equinox 1950.0), in an anonymous galaxy whose position is
R.A. = 23h48m25.75, Decl. = +8 24'06.6. SN 1988S was at mpg about 19
on Aug. 24.06 UT and mpg about 20 on Sept. 7.04.
1988 OCTOBER 1 DEADLINE FOR HST PROPOSALS
H. S. Stockman, Space Telescope Science Institute, writes:
"Recent changes in the Shuttle manifest have necessitated reordering
the launch of the Hubble Space Telescope from 1989 June to 1990 Feb.
The HST Program has received assurances that following the time-
critical launch windows for Magellan (early 1989) and Galileo (late
1989), HST will be NASA's highest priority science mission. In order
to provide as early a launch as possible, the HST Project, Kennedy
Space Flight Center and Johnson Space Center will maintain a high
state of readiness which would be required to launch HST as early as
1989 Aug., should the opportunity arise. In order to support the
early launch possibility, STScI is retaining the 1988 OCT. 1 DEADLINE
for proposals for general observer science programs to be carried out
in the period starting seven months after HST launch. Proposals must
be received at STScI by 1988 Oct. 1 in order to be considered for the
first cycle of general observations. To assist last-minute
preparations, STScI will have a toll-free number to handle general
science user questions as of Sept. 15. This number (800-544-8125) may
be reached from anywhere in the U.S. In addition, science user
questions may also be directed to the User Support Branch
(301-338-4723 or -4413). These lines will be manned during
12h30m-21h30m UT (Monday-Friday). Questions concerning GO grant proposals
can be directed to the Grants Administrator, telephone 301-338-4817."
NSV 6708
P. Whitelock, South African Astronomical Observatory, reports:
"M. Feast obtained the following infrared magnitudes on Sept. 8.7
UT: J = 6.83, H = 5.96, K = 4.66, L = 2.74. For comparison, mean
values for the first six months of 1988 were J = 6.04, H = 5.36, K =
4.35, L = 2.68. Such behavior (large change in J, little or no change
in L) is typical of an R CrB-type variable star."
1988 September 9 (4651) Daniel W. E. Green
