SUPERNOVA 1998V IN NGC 6627 (=Q1998/023)
On March 10 Mark Armstrong reported a possible supernova in
NGC 6627 but approaching twilight prevented confirmation by others.
Mark again imaged the object on Mar 12 and, following an appeal
to our checking team under reference Q1998/023 Tom Boles also
secured images on that date. Subsequently the Central Bureau have
issued the following message:

G. M. Hurst, Basingstoke, England, reports the discovery of an
apparent supernova (mag about 16) by Mark Armstrong, Rolvenden, on
an unfiltered CCD image obtained on Mar. 10.219 UT with a 0.20-m
reflector in the course of the U.K. Nova/Supernova Patrol.  An
image obtained on Mar. 12.115 by Armstrong yields mag 15.5 and the
following position:  R.A. = 18h22m37s.40, Decl. = +15o42'08".4
(equinox 2000.0), which is about 30" northwest of the centre of NGC
6627.  The object is not present in the Vickers CCD atlas or the
Palomar Sky Survey, nor does it appear on earlier U.K. patrol
images obtained during 1997 July 28-Oct. 21.  T. Boles,
Wellingborough, England, imaged the galaxy on Mar. 12.156, also
finding SN 1998V near mag 15.5 (unfiltered CCD).  Hurst further
reports that there is no star present in the USNO A1.0 catalogue to
mag 19.

S. Nakano, Sumoto, Japan, forwards the following precise position
end figures and magnitude for SN 1998V, measured by Y.Kushida from
a CCD image taken by R. Kushida on Mar. 13.75 UT with a 0.40-m
reflector at Yatsugatake South Base Observatory:
37s.40, 07".7, V = 15.1.
IAUC 6841

Editor: This is the seventh supernova found by patrol members and
the second by Mark Armstrong to whom we extend our sincere
congratulations.
