VSNET Weekly Campaign Summary *** Last week news *** (new targets) SN 2000dx (RA = 02h18m26s.88, Dec = +05d39'02".0) H. Yamaoka forwarded a content of IAUC 7514 which reports a new supernova, SN 2000dx. SN 2000dx was discovered on October 30.3 UT at mag about 17.3 and became slightly brighter on the next day. The position is about 8" east and 12" south of the nucleus of ring-shaped spiral galaxy UGC 1775. The spectrum of SN 2000dx shows that it is of type Ia a few days before maximum. Typical SN Ia on this galaxy is mag about 17.1. If it will rise from the discovery magnitude, it should have a bright nature. Nova in M31 (RA = 00h42m57s.17, Dec = +41d07'15".4) The Remanzacco Observatory team found a nova in M31 at the magnitude of 17.6 on October 22.9. It was not present on other frames of the same region taken with our instrumentation on September 1, 7, 8, 9 and 22 (vsnet-campaign-nova 88). Following this, F. Ewalt reported no object can be seen in his image taken September 5 and there is a "possible" stellar object dimmer than magnitude 18 in his October 24 image (vsnet-campaign-nova 89). The Remanzacco Observatory team again performed CCD observation on November 1 and estimated the magnitude of 18.7 (vsnet-campaign-nova 87). V2051 Oph (RA = 17h08m19.1s, Dec = -25d48m31.1s) According to R. Stubbings on October 27, the eclipsing SU UMa-type dwarf nova V2051 Oph is undergoing an outburst. The brightness suggests a superoutburst, however it faded rather rapidly. On November 5, R. Stubbings and P. Nelson reported the magnitudes fainter than 12.2 and 12.5, respectively (vsnet-campaign-dn 237). TY Psc (RA = 01h25m36s.87, Dec = +32d23'05".3) As reported by J. Ripero on October 28, the SU UMa-type dwarf nova TY Psc is undergoing a superoutburst (vsnet-campaign 545). The outburst is now undergoing, and the current magnitude is about 12.6 (vsnet-campaign-dn 235). V344 Pav (RA = 19h16m10.21s, Dec = -62d35'54".4) The dwarf nova V344 Pav is in outburst. R. Stubbings reported the magnitude of 14.4 on November 3. The last outburst was reported in 2000 July. Since little is known about this object, we encourage time-resolved photometry (vsnet-campaign 548). HX Peg (RA = 23h40m23s.37, Dec = +12d37'44".0) The observation by R. Stubbings on November 3 (14.0: mag) indicates possible brightening of this object. No bright outbursts have been observed since the early October outburst. This star may be experiencing a low state like that of RX And. More observations are clearly needed (vsnet-campaign 549). V1028 Cyg (RA = 20h00m52.13s, Dec = +56d56'22.3") The SU UMa-type dwarf nova V1028 Cyg is in outburst as reported by G. Poyner at 13.9mag on November 3. The last outburst was in 1999 September. Follow-up observations of the present outburst is also highly encouraged (vsnet-campaign 550). The current magnitude is about 14.3mag (vsnet-campaign 552, -dn 233). IX Dra (RA = 18h12m32s.2, Dec = +67d04'41") T. Vanmunster performed CCD observations on IX Dra whose outburst was reported on October 25 by M. Reszelski and the resulting real-time light curve clearly shows the presence of a 0.22 mag modulation, to be attributed to superhumps (vsnet-campaign 551). Based on his 6.45hr observation, the superhump period is calculated to be 0.068d. Observations from other observatories therefore would be highly appreciated, to further study the outburst behaviour of this interesting UGSU type CV (vsnet-campaign 551). As reported by T. Kinnunen, the September outburst lasted at least for four days, which might suggest another superoutburst. If the September outburst was a genuine superoutburst, the interval of subsequent superoutbursts becomes as short as 49 d, which is pretty close to that of ER UMa (vsnet-campaign 553). (continuous targets) Delta Vel (RA = 08h44m42s.1, Dec = -54d42'30") S. Otero reported results by A. Jansen on October 31 - November 1 and 2, which detected an eclipse at the expected time (vsnet-campaign-deltavel 11). He also calculated a candidate of the period to be 45.15667 day and predict the next eclipse on November 21 18.30 (UT) and December 17 2.40 (UT) (vsnet-campaign-deltavel 13). B. Fraser reported a little dimmer magnitude of V=1.99 on November 4 1.30 (UT) (vsnet-campaign-deltavel 14). B. Fraser reported his November 4 observation yields V=2.01mag and commented it may be showing some variability or the given brightest of 1.95 is slightly wrong (vsnet-campaign-deltavel 17). KW And (RA = 02h35m17s.991, Dec = +41d14'02".47) T. Kato and H. Iwamatsu confirmed the magnitude is going down to about 17.5mag on November 1st (vsnet-campaign-dn 228). RX J2315.5-3049 (RA = 23h15m31s.934, Dec = -30d48'45".53) T. Kato and H. Iwamatsu confirmed the magnitude is going down to about 16mag on November 1st (vsnet-campaign-dn 226). Although superhumps were observed, the outburst was terminated (vsnet-campaign-dn 230). IP Peg (RA = 23h23m08s.7, Dec = +18d24'59".1) M. Richmond commented the position written in the last VSNET Weekly Campaign Summary and in SIMBAD are incorrect (vsnet-campaign-dn 227). The above position is cited from Ritter H., & Kolb U. (1998), which presents the position consistent with the position roughly estimated by M. Richmond. The current long bright outburst began fading. The current magnitude is about 14.8 (vsnet-campaign-dn 236). BL Lac (RA = 22h02m42.86s, Dec = +42d16'37.6") The striking activity is still ongoing. During the last week, 14.1-14.6mag were reported (vsnet-campaign-blazar 89). 3C 66A (RA = 02h22m39s.6, Dec = +43d02'08") The bright state is still ongoing. During the last week, 14.3-14.6mag were reported (vsnet-campaign-blazar 88). *** General information *** Delta Vel S.
