COMET P/2008 R2 (SCOTTI)
J. V. Scotti, Lunar and Planetary Laboratory, reports his
recovery of comet P/2001 X2 (cf. IAUCs 7775, 7777) on Spacewatch
CCD images obtained with the 1.8-m f/2.7 reflector at Kitt Peak,
the object showing a coma diameter of 5" and a tail extending 0'.5
in p.a. 272 deg. The indicated correction to the prediction on
MPC 56802 is Delta(T) = -0.15 day.

Incidental astrometry from the Mt. Lemmon survey on 2007 Sept. 13
(mag 20.8-22.3) and 2007 Oct. 8 (mag 21.6-21.9), and from the
Spacewatch survey on 2008 Aug. 7, are included with the current
astrometry on MPEC 2008-R30, together with revised orbital elements
and an ephemeris.
V466 ANDROMEDAE
H. Yamaoka, Kyushu University, reported the discovery by K.
Itagaki (Yamagata, Japan) of a possible nova on a CCD image taken
on Sept. 1.6 UT with a 0.21-m reflector in the course of his sky
survey, with a confirming unfiltered CCD image taken on Sept. 1.603
with a 0.60-m reflector that yields mag about 12.7 and the
following precise position: R.A. = 2h00m25s.40, Decl. =
+44o10'18".7 (equinox 2000.0). A patrol image from Jan. 26.532
shows nothing brighter than mag 17.5 at this position; there is a
very faint star (red mag 20.4, blue mag 21.2) in the GSC 2.3
catalogue with position end figures 25s.44, 19".1. Additional
confirming observations were published on CBET 1491, including
investigations that found nothing brighter than blue mag about 20.5
at the position of this variable. S. Korotkiy, Moscow, and
colleagues report that photometry shows a light curve with
amplitude 0.13 mag and period 0.055(1) day. N. N. Samus, Institute
of Astronomy, Moscow, informs us that this variable has been
assigned the designation V466 And.
P. Challis and R. P. Kirshner, Harvard-Smithsonian Center for
Astrophysics; and P. Garnavich, University of Notre Dame, report
that a spectrum (range 350-730 nm) of V466 And was obtained with
the 1.5-m Tillinghast telescope (+ FAST spectrograph) on Sept.
3.497 UT, showing a strong blue continuum with H_alpha and H_beta
in emission. Later Balmer lines are a combination of broad
absorption and weak emission. The FWHM of H_alpha is 600 km/s.
Also seen are He I 492.1-, 587.5-, 667.8-, 501.5-, and 706.5-nm and
He II 486.1-nm. The spectrum is that of a dwarf nova in outburst.
