SUPERNOVA 2002dp IN NGC 7678
A. Klotz, Guitalens, France, reports the discovery of an
apparent supernova (mag about 15.1 +/- 0.4) on CCD images (limiting
mag about 17.0) taken on June 18.09 and 19.02 UT with a 0.20-m
reflector. SN 2002dp is located at R.A. about 23h28m30s.4, Decl.
about +22o25'44" (equinox 2000.0), which is 30" east and 22" north
of the nucleus of NGC 7678. The new object is not present on
Palomar Sky Survey images or on an image taken on 2001 Sept. 11.94.
W. Li, University of California, reports that SN 2002dp appears at
mag about 15.0 on a KAIT image taken on June 19.5 UT, from which
the following position end figures were measured: 30s.12, 38".8
(equinox 2000.0), or 30".8 east and 21".7 north of the nucleus of
NGC 7678. A KAIT image taken on 2001 Dec. 28.3 showed nothing at
this position (limiting mag about 19.0).
SUPERNOVA 2002dq IN NGC 7051
D. Hutchings and W. D. Li, University of California at
Berkeley, report the LOTOSS (cf. IAUC 7906) discovery of an
apparent supernova on unfiltered KAIT CCD images taken on June 18.5
(mag about 17.0) and 19.4 UT (mag about 17.1). SN 2002dq is
located at R.A. = 21h19m49s.95, Decl. = -8 46'39".8 (equinox
2000.0), which is 20".4 west and 19".0 north of the nucleus of NGC
7051. A KAIT image taken on June 9.5 showed nothing at this
position (limiting mag about 18.0).
1E 2259+586
V. M. Kaspi, McGill University and Massachusetts Institute of
Technology; and F. P. Gavriil, McGill University, report the
detection with the PCA aboard RXTE of short x-ray bursts from the
direction of the anomalous x-ray pulsar 1E 2259+586 (cf. IAUC
3745). The Chandra-determined position for this pulsar is R.A. =
23h01m08s.295, Decl. = +58o52'44".45 (equinox 2000.0; uncertainty
0".60 in radius, 99-percent confidence; Hulleman et al. 2001, Ap.J.
563, L49). The bursting behavior was detected during a routine
15000-s duration monitoring observation that began on June 18.652
UT. In this observation, about 45 bursts were detected, most of
which had duration < 1-2 s, reminiscent of those seen in soft
gamma-ray repeaters. The mean 1-s flux per burst is approximately
10**-8 erg cm**-2 s**-1 (2-20 keV). Observations at other
wavebands are encouraged.
