======================================================================
* Class: 1 = primary target, 2 = secondary target, 3 = optional target
* Data: data request, 1 = VSNET core team, data will be received by
campaign report list. 2 = as above, in collaboration with
Hachisu-san.
(1) OU Vir: slowly fading stage with late superhumps. Still a good target
for a large telescope (mag 18).
We are also collecting data on the new variable star (see
vsnet-chat 6292: new eclipsing star in the OU Vir field
= USNO B1.0 0892-0239905. This object is certainly a W UMa-type
eclipsing binary. If you have data, send them to vsnet-campaign-report
(preferably in separate reports from OU Vir submissions).
(2) PU CMa: superoutburst. Great if you can manage to get a 2hr run
each night.
(3) IM Nor: probably eclipsing recurrent nova. Cover a few orbital cycles
(once or twice in a week, during the upcoming dark runs).
Berto Monard reported that it has faded to mag 17.0. Observations with
a large telescope are highly wanted at this stage!!
Berto's image (helpful for identification) is posted at:

(4) SX LMi: fading more rapidly than expected. Either normal outburst
or a precursor to a superoutburst. Observe if it it rebrightens!
(5) V660 Her: significantly faded (now mag 16-17). Although the behavior
suggests a normal outburst, there is still a possibility for
rebrightening to a superoutburst. Will be moved to top-priority if
it rebrightens.
(6) TV Crv: post-superoutburst stage. Rebrightening within a week
expected.
(7) RX Vol: watch if it rebrightens. Will be dropped from the list soon.
(8) MV Lyr: brightest in the recent decade(s). Would be a good target
(for late hours) for northern telescopes on these bright nights.
(9) CR Boo: recurring normal outbursts, or the start of a new supercycle?
(10) V729 Sgr: eclipse ephemeris (times are UT, geocentric)

Continued optional target (of potential opportunity): IY UMa
Please closely watch vsnet-alert and vsnet-outburst for other new
outbursts.

*** Notice ***
This list is "read-only", i.e. it is used only for announcement of
the target lists. Other information, as well as reports and discussions
on particular targets, should be directed to the appropriate VSNET campaign
sub-lists (e.g. vsnet-campaign-dn for dwarf novae).
We have also set up a separate list for "privately" receiving
campaign observations. Nightly time-series observations, which have been
report to me, Ishioka-san or Uemura-san, should be now directed to
---------------------------------------------------
vsnet-campaign-report@ooruri.kusastro.kyoto-u.ac.jp
---------------------------------------------------
Reports sent to this address will be delivered to the VSNET campaign
local staffs, including Ishioka-san, Uemura-san and me, and are expected
to be more convenient than personal e-mails to separate addresses.
