COMET 1999 T2
     F. Shelly reports the discovery by LINEAR of a comet.
Additional observations have been reported following posting on the
NEO Confirmation Page:

SUPERNOVA 1999eg IN IC 1861
     S. Jha, P. Garnavich, P. Challis, and R. Kirshner, Harvard-
Smithsonian Center for Astrophysics, report that a spectrum of SN
1999eg (cf. IAUC 7275), taken by P. Berlind on Oct. 13.4 UT with
the F. L. Whipple Observatory 1.5-m telescope (+ FAST spectrograph),
shows it to be a type-II supernova near maximum light.  The
spectrum exhibits a blue continuum with P-Cyg Balmer lines.
Cross-correlation of the host galaxy spectrum with an absorption-
line template yields a recession velocity of 6570 +/- 50 km/s for
IC 1861.  The supernova expansion velocity, measured using the
H-beta line profile, is 7200 km/s.
