SUPERNOVA 2001ie IN UGC 5542
A. Dimai, Cortina d'Ampezzo, Italy, reports the discovery by
A. Bincoletto, San Dona di Piave, Italy, of an apparent supernova
(mag about 16.5) on an image taken on Dec. 9.13 UT with a 0.30-m
f/5 reflector (limiting mag about 17.5). SN 2001ie is located at
R.A. = 10h16m50s.70, Decl. = +60o16'44".5 (equinox 2000.0), which
is about 15" west and 15" south of the nucleus of UGC 5542. A
confirming image taken on Dec. 10.02 with the 0.5-m telescope at
Col Drusci Observatory shows the new object at mag 16.1. An image
taken by Bincoletto on Jan. 21 showed nothing at the position of
the new object (limiting mag about 17.5), and it does not appear on
Palomar Sky Survey red and blue plates.
SUPERNOVA 2001if NEAR MCG +06-6-43
G. M. Hurst, Basingstoke, England, reports the discovery by T.
Boles, Coddenham, England, of an apparent supernova (mag 17.2) on a
30-s unfiltered CCD image taken on Dec. 9.986 UT in the course of
the U.K. Nova/Supernova Patrol with the 0.36-m 'A' Schmidt-
Cassegrain reflector. The new object, which appeared at similar
brightness on images taken on Dec. 10.016 and 10.788, is located at
R.A. = 2h28m54s.93, Decl. = +38o05'52".7 (equinox 2000.0; average
from the three images), which is 70" west and 3" south of the
nucleus of MCG +06-6-43. M. Armstrong, Rolvenden, England, reports
that a CCD image taken on Dec. 10.785 also shows the new star.
Boles notes that SN 2001if is absent from his master image taken on
Sept. 10.997 (limiting mag 18.5) and was not recorded on Palomar
Sky Survey images taken in 1986 (red, limiting mag 21) and 1993
(blue, limiting mag 20). Hurst adds that MCG +06-6-43 is the
brightest galaxy in the discovery field, but there are several
other galaxies nearby and the parent galaxy is not entirely
certain.
CATALOGUE OF COMETARY ORBITS 2001

America). There is also an e-mail edition (with just the basic
orbital information) for 75.00. Orders should be sent to Mailstop
18, Smithsonian Astrophysical Observatory, Cambridge, MA 02138,
U.S.A., by FAX to +1-617-495-7231 or by e-mail to
mlohmiller@cfa.harvard.edu. Payment can be by credit card or by
check made payable to Smithsonian Astrophysical Observatory.
