NOVA SCORPII 2005
G. Pojmanski, Warsaw University Astronomical Observatory,
reports the ASAS discovery (cf. IAUC 8402, 8495) of a possible nova
on CCD images obtained with a 180-mm-focal-length (65-mm-aperture)
telephoto lens, giving the new object's position as R.A. =
17h44m22s, Decl. = -34o16'.5 (equinox 2000.0 presumed), which is
noted as being in an area crowded with nearby stars; V magnitudes
for the new object: July 23.287 UT, [14; 25.284, 9.11; 26.296,
8.98; 26.311, 8.98. S. Nakano, Sumoto, Japan, reports the
independent discovery of this new object at mag 8.7 by Hideo
Nishimura (Kakegawa, Shizuoka-ken, Japan) on two 30-s Kodak T-Max
films taken on July 26.565 with a Pentax 6x7 camera (+ 200-mm f/4.0
lens), with position end figures given as 22s, 15'59" (equinox
2000.0); nothing was visible at this location on Nishimura's survey
films taken on July 20 (limiting mag 11). Nakano also forwards the
following precise position from four unfiltered 20-s CCD frames
taken by N. Hashimoto and T. Urata, Bisei Spaceguard Center, around
July 26.596 using the 0.50-m f/2.0 reflector: R.A. = 17h44m21s.59,
Decl. = -34o16'35".7 (magnitude 8.6). Nothing is visible at this
location on Digitized Sky Survey images (no limiting magnitude
provided); the nearest USNO-A2.0 star (red mag 17.4) has position
end figures 21s.987, 35".85.
VARIABLE STARS NEAR GALAXIES
Further to IAUC 8570, M. Baek and W. Li report the LOSS
discovery of a variable star on unfiltered KAIT images taken on
July 22.35 (at mag 15.6), 23.35 (mag 15.6), and 24.40 UT (mag 15.7).
The variable star is located at R.A. = 21h43m32s.94, Decl. =
+46o12'22".2 (equinox 2000.0), which is 48".8 east and 108".9 south
of the nucleus of UGC 11800. A KAIT image taken on July 16.36
showed nothing at this position (limiting mag about 19.0).
E. Lee and W. Li also report the LOSS discovery of a variable
star located 111".1 east and 9".7 north of the nucleus of MCG
-04-35-5 on unfiltered KAIT images taken on July 25.19 (when the
new object was at mag 15.8) and 26.18 UT (mag 15.9). This second
variable is located at R.A. = 14h43m35s.30, Decl. = -23o26'30".6
(equinox 2000.0). A KAIT image taken on 2004 May 24.20 showed
nothing at this position (limiting mag about 19.0).
COMET 168P/2005 N2 (HERGENROTHER)
This comet (P/2005 N2 = 1998 W2; cf. IAUC 8560) has been given
the permanent numbering 168P (MPC 54523).
