*** VSNET campaign selected current target list 2003 May 12 ***
Object Class Position Type State Data Remark
====================================================================

OU Vir 1 equatorial, UGSU+E superoutburst 1
whole night
TV Crv 2 equatorial - UGSU superoutburst 1 (1)
southern (mag 13.2)

IY UMa 3 northern UGSU+E quiescence 1 (3)
CR Boo 3 northern HeDN oscillating 1 (4)
====================================================================
* 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 and TV Crv coverage is becoming comparatively
important; 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"). The moon getting too bright, and we had
better skip this target unless you have a big telescope.
(3) 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).
(4) CR Boo: highly variable after a "superoutburst". Short-term large
amplitude variation has been reported. Worth observing if there is
no competing target.
Ohter potential targets in outburst: NSV 10934 (will fade soon),
BF Ara (superoutburst; no special need for observation this time),
V729 Sgr (fading). V373 Cen and V478 Sco are less likely promising
targets. RY Ser (in outburst) was observed in the past showing no
apparent superhumps, but may deserve independent confirmation.
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

---------------------------------------------------
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.
