REPORTED NOVA IN CEPHEUS
On June 3 Y. Kozai, Tokyo Astronomical Observatory, telexed
that Minoru Honda, Kurashiki, had discovered on object of mag 7.5,
unconfirmed but presumably a nova, on a (single?) Tri-X exposure
obtained on June 1. The object was not found (i.e., was not
brighter than mag 11) on May 29 and earlier. H. Kosai subsequently
measured the following position from the June 1 plate:
1983 UT R.A. (1950.0) Decl. mpv
June 1.63715 22 11 58.03 +56 46 19.9 7.5
Noting that the object was very near the field of YZ Cep, J.
Mattei, AAVSO, informs us that J. Morgan, Prescott, AZ, has confirmed
a stellar object near the reported approximate position and
has obtained the following magnitude estimates: June 4.31 UT,
10.0; 5.24, 10.1. No further positive or negative reports were
available, and on the basis of Morgan's observations the Central
Bureau alerted telegram subscribers. A telex received today from
Tokyo notes that no object brighter than mag 13.5 appears at the
position on further exposures on June 3.6 by Honda and also with
the Kiso Schmidt telescope.
EDITORIAL NOTICE
Many modern astrophysicists, particularly those who work at
wavelengths outside the optical region, habitually contact us for
updated information relating to real or reputed discoveries of
both comets and novae. A handful of individuals greatly assist
us, not only in confirming, but also in obtaining accurate positions
of comets and unusual minor planets. However, there is also
a severe need for observers (particularly in the northern hemisphere)
who can provide reliable spectroscopic and astrometric
observations of as-yet-unconfirmed novae and supernovae (and who
will also inform us of relevant negative observations). Rapid
communication and response, most preferably by telex, is essential.
More than ever before, the Bureau is faced with the problem of
deciding whether to transmit a report that may be erroneous or to
withhold one that may be real. As an incentive to those professional
astronomers willing to assist us in this way, we are prepared
to waive line charges, not only for the publication of
astrometric observations in these Circulars, but also for that of
spectroscopic data promptly communicated following our requests.
