Results of the 1966 Search
Ten supernovae were found with the Palomar telescopes in 1966.
They are listed in Table I and shown on Plate 1. The scale of all the
photographs is the same as that indicated on No. 1, except No. 7
which is different and is marked separately. Estimates of the apparent magnitudes of the supernovae and of the parent galaxies were
made by the various observers. Galaxy types in the fourth column
were estimated from 48-inch Schmidt plates. The tenth column contains the estimated magnitudes of the supemovae for the dates
shown. They are not magnitudes at maximum brightness, although
some of the supernovae must have been near maximum when found,
since many fields were photographed once a month. The eleventh
column identifies the first observer, Κ = Kowal, R = Reaves, Ru =
Rudnicki. The next to the last column gives the number of the supernova in my master list of all supernovae discovered since 1885
(Zwicky 1958, 1964).
No. 4 was discovered independently by M. Lovas at the Konkoly
Observatory, Budapest, Hungary.
No. 7 was discovered on the Sky Survey Plate No. 1244 when compared with 18-inch Schmidt film in the preparation of Vol. 6 of the
Catalogue of Galaxies and of Clusters of Galaxies.
As in the past ( see Zwicky 1966 ), the Palomar search has been
supported in part by a grant from the National Science Foundation
in Washington, D. C. This search forms a part of the international
cooperation among a dozen observatories in various countries of
both hemispheres which has been organized by the Committee for
Research on Supemovae of Commission 28 of the I AU. It may be
remarked in parentheses that the members of the Committee have
been very active during the year in reducing many of the available
