COMETS C/1999 L5 (SOHO) AND C/1999 M1 (SOHO)
     D. A. Biesecker, SM&A Corporation and Goddard Space Flight Center,
reports his detection and measurements (reduced by the undersigned) of
two more apparent Kreutz sungrazing comets in images obtained with both
the C2 and C3 coronagraphs aboard SOHO.  Neither comet showed evidence of
a tail.  Further details are given on MPEC 1999-M23 and 1999-M24.

1999 LD31 AND 1999 LE31
     MPEC 1999-M28 and 1999-M29 provide detailed information about two
apparently asteroidal objects, 1999 LD31 and LE31, discovered by LINEAR
on June 8 and 12, respectively (with prediscovery observations of the
latter on May 17), and followed extensively by observers using The NEO
Confirmation Page.  In each case the orbit has been found to be retrograde:
1999 LD31 has a = 21.9 AU, e = 0.89, i = 160 deg, H = 13.9; 1999 LE31 has
a = 8.0 AU, e = 0.46, i = 152 deg, H = 12.3.  All observers have consistently
reported 1999 LD31 to be asteroidal, and only one observer has suggested
that 1999 LE31 may have cometary appearance (although this is unconfirmed).
In particular, A. Fitzsimmons, Queen's University, Belfast, reports that
250-s exposures in 1" seeing by S. Collander-Brown and S. Lowry with the
1-m Kapteyn telescope at La Palma on June 15 show both objects clearly to
be point sources.


NOVA IN NGC 6822
     J. Y. King and W. D. Li, University of California at Berkeley,
on behalf of the Lick Observatory Supernova Search (cf. IAUC
6627, 7126) with the 0.8-m Katzman Automatic Imaging Telescope (KAIT),
report the discovery of an apparent nova in NGC 6822, a dwarf
irregular galaxy that is probably in the Local Group.  The nova
was discovered on unfiltered images taken on June 23.40 and 23.44 UT
(mag about 17.3) and confirmed by an observation made on June 24.38
(mag about 17.0).  The new object is located at R.A. = 19h45m00s.31,
Decl. = -14o50'10".3 (equinox 2000.0).  A KAIT image of the same
field on June 19.4 UT (limiting magnitude about 18.5) showed nothing
at the position of the nova.  A finding chart for the nova can be
found at the URL http://astron.berkeley.edu/~bait/n6822.gif."
