Total visual magnitude estimates by J. Bortle, Brooks Observatory
(0.3-m reflector): Aug. 17.35 UT, 10.4; Sept. 1.37, 10.4; 4.35,
10.9; 10.02, 11.1. The comet may thus be brighter than predicted.
NOVALIKE OBJECT IN VULPECULA
M. Muminovic, Astronomical Observatory, Sarajevo, communicates
the following red photographic magnitudes: 1974 July 15.80 UT, [15;
1979 Aug. 23.87, 9. M. Cavagna and S. Baroni, Milan, suggest that
the visual magnitude oscillated between 8.8 and 9.2 on Sept. 4.9 UT.
NOTICE TO TELEGRAM SUBSCRIBERS
Effective immediately, the per-message cost to telegram subscribers
outside North America will be $7.00 by telex or delayed-delivery
cablegram and $11.00 by full-rate cablegram; there will be
a surcharge in the case of very long full-rate cablegrams. North
American rates remain at $7.00 for full-rate telegrams and $2.00
for mailgrams, but the TWX/telex rate will be increased to $3.00.
