SUPERNOVA 1994ah IN ESO 356-G19
R. H. McNaught reports his discovery of an apparent supernova
(mag about 18) on a U.K. Schmidt Telescope I plate taken on Oct. 13.
SN 1994ah is at R.A. = 2h54m35s.26, Decl. = -34o06'45".8 (equinox
1950.0; uncertainty 0".3 in each coordinate), which is 12".4 east
and 2".5 north of the galaxy's center. No image appears in this
position on the ESO B or R survey plates, the Whiteoak extension of
the Palomar Sky Survey, the SERC J survey, or a U.K. Schmidt plate
taken on 1993 Oct. 21. Confirmation was obtained by N. B. Suntzeff
on Dec. 12.2 UT with the Cerro Tololo 4-m telescope; his
spectrophotometry (range 320-750 nm, resolution 700) shows this
object to be a type-Ia supernova about 4 months past maximum. Its
spectrum appears identical to the nebular spectrum of SN 1981B at
the same phase of evolution (Branch et al. 1983, Ap.J. 270, 123).
NOTICE TO SUBSCRIBERS
Owing to increased postal rates to be introduced next month,
it is necessary to increase the subscription rates for these
Circulars. The new monthly rates will be 15.00 (regular or
invoiced) and 9.00 (special or non-invoiced). However, the monthly
charge for the Computer Service/e-mail delivery will be decreased
to 10.00 (regular) and 6.00 (special). This reduction means that
there will be no change in the combined cost to those who subscribe
to both the printed and e-mail versions. A subscriber who receives
only the e-mail version and who has paid ahead is invited to
renegotiate the expiry date for his or her account by sending an e-
mail message to iausubs@cfa.harvard.edu by 1995 Jan. 27, indicating
either the account number or the e-mail address used for the
delivery of the Circulars.
Long-term subscribers will note that the cost of a Computer
Service/e-mail subscription is as low as it has ever been, and it
could be reduced further if more people who read "pirated" versions
of these Circulars were to participate. The Computer Service has
many features now it did not have when it started in 1984, including
a complete set of the Circulars back to 1982 and a complete cross-
referenced index back to 1922. E-mail subscribers who do not have
instructions for using the Computer Service should request their
passwords by e-mailing the aforementioned address.
