[vsnet-campaign 1181] VSNET Weekly Campaign Summary
VSNET Weekly Campaign Summary
*** Last week news ***
(new targets)
Nova Cen 2001 (RA = 13h55m41s.27, Dec = -64d15'57".9)
W. Liller reported a possible nova of 8.6mag on October 1
(vsnet-campaign-nova 594, 595, 596, 602, 603, 604, 605).
A. Jones, A. Pearce, and M. Mattiazzo reported their confirmation
just after the discovery (vsnet-campaign-nova 597, 598, 600, 601).
The object is now around 9.8mag (vsnet-campaign-nova 599, 606, 609).
EF Peg (RA = 21h15m04s, Dec = +14d03'50")
As reported by E. Muyllaert in [vsnet-alert 6734], the SU UMa-type
dwarf nova EF Peg started its new rare outburst of 11.1mag on
October 3. EF Peg is a strange SU UMa-type star in the point
of its long cycle of superoutburst with a long orbital period of
near 2 hours, the edge of the "period gap" of CVs (vsnet-campaign 1180,
vsnet-campaign-dn 1674). D. Starkey's data on October 6 detected
a probable superhump, which strongly indicates the current outburst is
a genuine superoutburst (vsnet-campaign-dn 1688). The object is now
about 11.1mag and the outburst is still ongoing (vsnet-campaign-dn 1676,
1678, 1682, 1685).
SN 2001ep (RA = 04h57m00s.26, Dec = -04d45'40".2)
IAUC 7727 tells that the KAIT team discovered SN 2001ep on
October 3 (17.1mag) and 4 (16.8mag). The recession velocity of
the host galaxy NGC 1699 is measured as 3900 km/s, from which
the expected maximum of typical SN Ia is mag about 15.3
(vsnet-campaign-sn 256).
SN 2001eq (RA = 23h04m56s.78, Dec = +19d33'04".8)
IAUC 7728 tells that the KAIT reported SN 2001 first detected
on September 12 at 18.7mag. The object was 17.2mag on October 4
(vsnet-campaign-sn 257).
(continuous targets)
V1548 Aql (RA = 19h07m28s.42, Dec = +11d44'45".8)
The object rebrightened to 13.0mag on October 4
(vsnet-campaign-nova 607).
SN 2001el (RA = 03h44m30s.57, Dec = -44d38'23".7)
The object is now bright at about 12.6mag (vsnet-campaign-sn 258).
TY Psc (RA = 01h25m36s.87, Dec = +32d23'05".3)
The superoutburst was terminated around October 1 and 2
(vsnet-campaign-dn 1673).
V4740 Sgr = Nova Sgr 2001 No. 3
(RA = 18h11m45s.82, Dec = -30d30'49".9)
The slow fading continues (vsnet-campaign-nova 608, 610).
MV Lyr (RA = 19h07m15s.93, Dec = +44d01'10".7)
The object is now around 13mag (vsnet-campaign-nl 44).
WZ Sge (RA = 20h07m36s.53, Dec = +17d42'15".3)
The late superhumps are still reported, and the international
campaign is ongoing (vsnet-campaign-dn 1672, 1675, 1677, 1683,
1684). The humps were again growing on October 1 and 2
(vsnet-campaign-dn 1669, 1670). On October 3, eclipses became
prominent and then the amplitude of humps decreased
(vsnet-campaign-dn 1679). The eclipse feature has been becoming
weaker as the system faded (vsnet-campaign-dn 1680). The emergence
of humps (~0.4mag) is reported on October 7 (vsnet-campaign-dn 1686).

space observatories. A web-page has been setup listing the scheduled
observations so far which we intend to keep up to date at:
