NOVA CIRCINI 1999
     W. Liller, Vina del Mar, Chile, reports his discovery of an
apparent nova (m_pv = 7.7) on Technical Pan photographs taken with
an 85-mm camera lens (+ orange filter; via PROBLICOM) on Aug.
23.0110 and 23.0125 UT.  CCD frames taken with a 0.20-m Schmidt
camera on Aug. 23.9717 yield a position of R.A. = 14h23m23s.6,
Decl. = -69o08'45".1 (equinox 2000.0; uncertainty +/- 0".5), at
which time the magnitude measured with a broadband V filter was
7.79.  Nothing brighter than mag 11.0 appears at this location on
two photographs taken on July 15.99.  A low-resolution spectrogram
obtained with the Schmidt (+ objective prism + CCD) on Aug. 23.9874
shows H-alpha in emission at a level about 0.85 times brighter than
the intensity of the surrounding continuum.  The modest strength of
this emission suggests that the nova outburst occurred only a day
or two earlier.  A. Pearce, Nedlands, W. Australia, reports the
star at visual mag 8.1 on Aug. 24.581, noting that nothing is
visible on the Digital Sky Survey field at the position of the
nova.  Other visual magnitude estimates:  Aug. 24.037, 7.5 (R.
Stubbings, Drouin, Victoria, Australia); 24.302, 8.4 (A. Jones,
Nelson, New Zealand).


SUPERNOVA 1999do IN MARKARIAN 922
     M. Modjaz and W. D. Li, University of California at Berkeley,
on behalf of the Lick Observatory Supernova Search (cf. IAUC 6627,
7126), report the discovery with the 0.8-m Katzman Automatic
Imaging Telescope (KAIT) of an apparent supernova in Mrk 922 (=
MCG +05-54-003) on unfiltered images taken on Aug. 20.3 (mag about
18.0) and 21.3 UT (mag about 17.4).  The new object is located at
R.A. = 22h53m29s.87, Decl. = +31o38'42".9 (equinox 2000.0), which
is 4".7 east of the nucleus of Mrk 922.  A KAIT image of the same
field taken on Aug. 16.3 (limiting mag about 19.5) showed nothing
at this position.


COMET 10P/TEMPEL 2
     Visual m_1 estimates:  Aug. 2.08 UT, 10.6 (J. Bortle,
Stormville, NY, 0.41-m reflector); 9.36, 9.5 (S. T. Rae,
Palmerston North, New Zealand, 0.25-m reflector); 13.85, 8.8 (M.
Reszelski, Szamotuly, Poland, 20x60 binoculars); 22.56, 9.2 (A.
Pearce, Nedlands, W. Australia, 20x80 binoculars).
