Dear all,

   The current "unusual" activity of U Gem has been one of topics in VSNET
(esp. vsnet-campaign-dn list).  We have been indeed conducting an extensive
campaign on this object, in order to see what is going on in the U Gem
accretion disk, and to see what will be its evolution at the start of the
next outburst.  We have been covering at least one per night eclipses
photometrically.  If the object baheves differently (e.g. apprarent rising),
we would be very grateful to hear the news immediately.  A summary of
recent U Gem is presented in the bulletin "News from VSNET", also posted
to the AAVSO discussion list.

   The coordinator of this campaign is R. Ishioka
(ishioka@kusastro.kyoto-u.ac.jp), to whom those who are interested in
the campaign should contact.
