[vsnet-alert 5865] U Gem outburst fading

[Taichi Kato <tkato>]

U Gem outburst fading

  The current outburst of U Gem is fading rather rapidly, in spite of
the long preceding quiescence period.  The outburst may by terminated
by this fade, but the 1985 outburst of U Gem (another outburst preceded
by a long quiescence) was probably associated with a dip during the
outburst.  Detailed follow-up observations are encouraged in order to
see whether a similar phenomenon happens.  As all observers may know,
the visual comparison star sequence for U Gem has a problem (esp. for
old ones).  Accurate photometry with CCD is also very helpful to
eliminate the effect caused by different comparison stars.
