[vsnet-outburst 10858] EF Peg superhumps

[Taichi Kato]

EF Peg superhumps

   Maehara-san and Ian Miller have reported time-series photometry.
Superhumps were well-recorded on Dec. 22.  There was also a hint
of superhump modulations on Dec. 21.  The periods determined from
Dec. 22 and the entire set have been significantly longer than the
formal superhump periods reported for 1991 and 1997 superoutbursts.
The mean period up to now is 0.08923(6) d, 2.6% longer than the
1991 period.  This long superhump period may be a result of
stage A superhumps.  Further observations are encouraged to qualify
the evolution of the period (note that EF Peg is one of rare long-P
systems without a canonical period decrease).
