====================================================================
* 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.
Two priority targets OU Vir (mag about 15) and RX Vol (mag about 15)
are unchanged. The RX Vol coverage is becoming sparce; please take
at least one superhump cycle (2 hr) each night to ensure period/Pdot
analysis.
(1) TV Crv: definite superoutburst of a large-amplitude SU UMa star.
Greg Bolt recorded beutiful superhumps. Alternative target when
OU Vir is too faint. Pdot determination is the next step for about
a week. Take at least one superhump cycle (1.5-2 hr).
(2) IM Nor: If possible, take time-series longer than 3 hours (to cover
at least one "eclipse"). Take at least a few eclipses before the
moonlight becomes overwhelming.
(3) V729 Sgr: eclipsing dwarf nova. Greg Bolt succeeded in observing
an eclipse during the current outburst. Possibly fading from an
outburst. The eclipse ephemeris is found to be sufficiently exact.
(4) IY UMa: outburst missed or long overdue? If an outburst occurs,
please observe it from the very beginning of the outburst.
(potential target of opportunity).
(5) CR Boo: highly variable after a "superoutburst". Short-term large
amplitude variation has been reported. Worth observing if there is
no competing target.
(6) AD Men: the identification has been corrected. See
http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/DNe/admen.html (star A = AD Men)
and resubmit observations if you measured a different star (likely
star B) in the past campaigns. Not particularly selected as the
current campaign target.
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.
