FSPACE CV Circular 1993.2 (FSPACE NO.3) Edited by N.Makiguchi
*** HIGHLIGHTS OF THE MONTH ***
First ever confirmed normal outburst of SW UMa!
Superoutburst of SU UMa (19-28)
Superoutburst of CY UMa (23-28) Taichi Kato detected superhumps in CY UMa
during its current outburst and confirms that it is a new SU UMa-type
variable. The previous superoutburst of this dwarf nova occurred in
December, 1991.
Dwarf novae in outburst were RX And(13-18 bright maximum), AR And(15-17)
HL CMa(15-25 long outburst), YZ Cnc(23-26)
CC Cnc(15-20 superoutburst!), IR Gem(24-25), X Leo(19-28 long outburst),
CN Ori(18-28), CZ Ori(20-25), IP Peg(Jan.30-Feb.5),
PG0943+521(10-15,22-27), Z Cam(in standstill)
V1974 Cyg (=Nova Cygni 1992) is fading slowly.
SU Tau shows a subtle fade by 0.2 to 0.3 mag. (Note added in proof: This
R CrB-type star reached around mv=11.0 at the end of March and seems to be
fading rapidly.)
FG Sge is steadily recovering from the current minimum.
* Note that this circular does not represent the official report of
VSOLJ or other organizations. This is a summary of variable stars
based on all the observations available to us.
