     R. Huber and F. Shelley, Lincoln Laboratory, Massachusetts
Institute of Technology, report the discovery by LINEAR of a comet
(discovery observation below) with a tail 42"-47" long in p.a. 12.5
deg.  Cometary activity has been confirmed via CCD observations by
A. Galad and L. Kornos at Modra on Feb. 1.8 (m_1 = 16.3, asymmetric
coma extending 15" toward p.a. about 30 deg) and 2.7 UT (slightly
diffuse with coma diameter about 10"), by J. Ticha and M. Tichy at
Klet on Feb. 2.7 (coma diameter 10"), and by T. Payer at
Duesseldorf, Germany, on Feb. 2.8 (coma visible, m_1 = 16.6).

SUPERNOVA 2002ao IN UGC 9299
     K. Kinugasa and H. Kawakita, Gunma Astronomical Observatory
(GAO); and H. Yamaoka, Kyushu University, report that a low-
resolution spectrum of SN 2002ao (IAUC 7809, 7810) was obtained on
Jan. 31.73 UT with the GAO 0.65-m telescope (+ GCS), showing a flat
continuum with notable absorption features at 570 and 610 nm.  The
spectrum closely resembles that of type-Ic SN 1999bz near maximum
light (IAUC 7162).

SUPERNOVA 2002H IN MCG -02-35-11
     D. C. Leonard, University of Massachusetts at Amherst; and
A. V. Filippenko, University of California at Berkeley, report that
inspection of a preliminarily reduced CCD spectrum (range 430-800
nm, resolution 0.7 nm), obtained with the Cerro Tololo 4-m
telescope on Jan. 22.36 UT by L. E. Kay (Columbia University), H. D.
Tran (Johns Hopkins University), and A. M. Magalhaes (Universidade
de Sao Paulo), shows that SN 2002H (cf. IAUC 7798) is a type-Ia
supernova about 2-3 weeks past maximum light.
