VSNET Weekly Campaign Summary *** Last week news *** (new targets) 4C 29.45 (RA = 10h10m05s.37, Dec = +40d00'20".4) M. Villata reported on October 9 that the highly polarized and OVV quasar 4C 29.45 (1156+295) experienced an exceptional radio outburst (vsnet-campaign-blazar 227). The slow fading was reported before the ratio burst by S. O'Connor (vsnet-campaign-blazar 228). RU Peg (RA = 22h14m02s.58, Dec = +12d42'11".4) Recently reported observations show unusually complex outbursts. The current magnitude is around 11.0mag (vsnet-campaign-dn 1702, 1708, 1716). V391 Lyr (RA = 18h21m11s.97, Dec = +38d47'43".0) Since October 6, a long, bright outburst of this object continues. The magnitude is around 14.1mag (vsnet-campaign-dn 1703). TX Tri (RA = 01h37m37s.24, Dec = +30d02'48".9) An outburst continues since October 11. The current magnitude is about 14.0mag (vsnet-campaign-dn 1717). CH Cyg (RA = 19h24m33s.07, Dec = +50d14'29".5) A sudden brightening to about 7mag was reported on October 14 (vsnet-campaign 1182). (continuous targets) Nova Cen 2001 (RA = 13h55m41s.27, Dec = -64d15'57".9) The fading speed became faster from October 8-9 (vsnet-campaign-nova 611, 615, 619, 622), and then around October 12, the reported magnitudes indicates possible oscillations between 11.1-11.6 (vsnet-campaign-nova 625). EF Peg (RA = 21h15m04s, Dec = +14d03'50") The superoutburst is still ongoing (vsnet-campaign-dn 1690, 1693, 1696, 1701, 1707, 1715). PKS 2155-304 (RA = 21h58m52s, Dec = -30d13'31") The object is still in the bright state at around 12.6mag (vsnet-campaign-blazar 229). V893 Sco (RA = 16h14m45s.26, Dec = -28d39'30".3) The object was reported to be slightly bright at 13.8mag (vsnet-campaign-dn 1691). V2275 Cyg= Nova Cyg 2002 No. 2 (RA = 21h03m02s.00, Dec = +48d45'52".9) The smooth fading continues. It is now about 12.3mag (vsnet-campaign-nova 613, 627, 630). V1548 Aql (RA = 19h07m28s.42, Dec = +11d44'45".8) The object faded from the rebrightening. The current magnitude is about 14.6mag (vsnet-campaign-nova 614, 626). SN 2001en (RA = 01h25m22s.90, Dec = +34d01'30".5) IAUC 7732 informed that SN 2001en is of type Ia, and reached its optical maximum around Oct. 10. The reported magnitude around maximum is about 15.0, which is somewhat brighter than the typical SN Ia (vsnet-campaign-sn 261, 262). SN 2001el (RA = 03h44m30s.57, Dec = -44d38'23".7) The SN seems to past the maximum and start fading (vsnet-campaign-sn 259). R. Knight reported 12.4mag on October 12 (vsnet-campaign-sn 260). delta Sco (RA = 16h00m19s.9, Dec = -22d37'17") Recent observations indicates the object becomes brighter again (vsnet-campaign-be 145). V4740 Sgr = Nova Sgr 2001 No. 3 (RA = 18h11m45s.82, Dec = -30d30'49".9) The fading continues. The nova is now around 10.2mag (vsnet-campaign-nova 612, 616, 617, 618, 620, 621, 624, 629). WZ Sge (RA = 20h07m36s.53, Dec = +17d42'15".3) The slow fading still continues and the international campaign is still ongoing (vsnet-campaign-dn 1689, 1692, 1695, 1699, 1706, 1713, 1714, 1718). It seems that slow modulations (hours to a day) seem to have appeared, which have not been observed before. The data on Oct. 4 show a previously unseen general trend of fading. The fading, however, did not continue on Oct. 5. The amplitude of humps reached a maximum on Oct. 7, and has significantly decreased on Oct. 8. The Oct. 8 run showed a general trend of brightening, in contrast to the Oct. 4 observation (vsnet-campaign-dn 1694). The late superhumps were still seen on October 9 and 10 with amplitudes of 0.1-0.2mag (vsnet-campaign-dn 1697). The fading speed seemed to become more rapidly around October 13 (vsnet-campaign-dn 1700, 1705). A. Henden reported V=14.32 on October 14 (vsnet-campaign-dn 1709). The light curve on Oct. 12 show very clear humps (0.3 mag) and narrow, sharp eclipses (vsnet-campaign-dn 1710). *** Future schedule *** WZ Sge campaign D.
