COMET C/1998 T1 (LINEAR)
     One of 17 fast-moving asteroidal objects reported by the
Lincoln Laboratory Near Earth Asteroid Research Team on Oct. 2
appears to be a long-period comet, according both to the retrograde
nature of its orbit and remarks by Y. Ikari (Moriyama, Japan;
relayed by S. Nakano) concerning the object's appearance, when he
observed it on Oct. 3 and 8 in response to the request in The NEO
Confirmation Page.  From the more complete information given on
MPEC 1998-T15, the discovery position, orbital elements and
ephemeris are extracted below:

VARIABLE STAR IN HERCULES
     E. Halderson, T. Shefler, M. Modjaz, J. Y. King, M. Papenkova,
W. D. Li, R. R. Treffers, and A. V. Filippenko, University of
California at Berkeley, report their discovery of a (probably
cataclysmic) variable star in our own galaxy during the course of
the Lick Observatory Supernova Search with the 0.8-m Katzman
Automatic Imaging Telescope (KAIT).  The variable star was found
and confirmed on unfiltered images taken on Oct. 5.2 (mag about
18.0) and 6.2 UT (mag about 17.8).  The object is located at R.A. =
18h14m14s.31, Decl. = +30o43'37".0 (equinox 2000.0).  A KAIT image
of the same field obtained on Sept. 19.2 shows nothing at the
position of the variable star (limiting mag about 19.5), nor does
the Digitized Sky Survey image of the field show anything at this
position.  A finding chart may be found at
