[vsnet-obs 991] QY Per in 1994

[tkato@kusastro.kyoto-u.ac.jp]

   T. Vanmunster has kindly provided me a summary of the 1994 outburst of
QY Per.

-- included message --

Here's the requested information on the 1994 outburst of QY Per, which
I have taken over from CVC 21.

   Judging from this information, it seems to me that the 1994 outburst
is a normal (short) outburst rather than a superoutburst as suggested
in CVC 54.  It is rather surprizing that this outburst may have surpassed
the brightest recorded outburst, but still seems to be a normal (short)
one.  A similar cases can be found in BZ UMa, DV UMa etc.  I have vague
impression that some TOADs behave unlike many TOADs, in that they rarely
show superoutbursts in spite of their very low outburst frequency
(this is just the opposite how WZ Sge-type dwarf novae usually behave).
Can someone comment on this?  Or are we only missing superoutbrusts?
I would be eager to know what has been the case of the 1995 outburst of
QY Per.
