VSNET Weekly Campaign Summary *** Last week news *** (new targets) AW Sge (RA = 19h58m37s.11, Dec = +16d41'28".7) M. Simonsen detected an outburst of the poorly known SU UMa star, AW Sge at 14.4mag on October 31. The last recorded outburst (superoutburst) was in 2000 July (vsnet-campaign-dn 2946). The brightness suggested a superoutburst (vsnet-campaign-dn 2949). Observations by the Nyrola team, however, indicated a rather rapid decline at a rate of 0.9 mag/d (vsnet-campaign-dn 2955). On October 31, T. Vanmunster reported irregular modulations with an amplitude of about 0.3mag, which are not superhumps (vsnet-campaign-dn 2956, 2958, 2960). After the fading, a possible rebrightening to 17.2mag on November 3 was reported by D. Starkey (vsnet-campaign-dn 2951, 2954, 2969). Confirmations are urged. PU Per (RA = 02h42m16s.1, Dec = 35d40'46") M. Simonsen reported on November 1 that the SU UMa-type dwarf nova, PU Per is undergoing a rare, bright (14.7mag) outburst. The last reported outburst of PU Per occurred in 1998 September. Its large outburst amplitude and long recurrent time suggest that the object may be related to WZ Sge-type stars (vsnet-campaign-dn 2959). In the light curve taken by D. Starkey, small-amplitude variations are likely present, while there is no distinct superhumps (vsnet-campaign-dn 2962). The time-series observation by G. Billings on November 2 yields a light curve showing a rather rapid linear fading, with 0.1-mag fluctuations. T. Kato commented that, judging from the behavior up to now and the short-term variations, the outburst may be a normal outburst, or a precursor outburst of an expected superoutburst (vsnet-campaign-dn 2963, 2967). The object further faded by 1.5mag on November 3, which supports that the outburst is a normal one (vsnet-campaign-dn 2970). SN 2002hh (RA = 20h34m44s.29, Dec = +60d07'19".0) SN 2002hh was discovered by the KAIT team on Oct. 31.1 UT (mag about 16.5) and confirmed on Nov. 2.1 (mag about 16.3). The position of the new object is about 61" west and 114" south of the nucleus of a face-on open spiral galaxy NGC 6946. NGC 6946 produced at least 6 SNe (1917A, 1939C, 1948B, 1968D, 1969P, and 1980K) in the last century. The brightest one of these six was SN IIL 1980K, whose maximum was B=11.6. It was below mag about 19.0 on Oct. 26.1. It should definitely be in the rising phase (vsnet-campaign-sn 491). V344 Ori (RA = 06h15m18.94, Dec = +15d30'59".9) M. Simonsen detected an outburst of V344 Ori at 14.1mag on November 1. V344 Ori is an unusual dwarf nova which underwent an exceptionally bright outburst in 2000 January (vsnet-campaign-dn 2959, 2964). The Kyoto team confirmed the outburst on November 1 (vsnet-campaign-dn 2965). DM Lyr (RA = 18h58m45s.02, Dec = +30d15'39".9) The SU UMa-type dwarf nova DM Lyr experienced an outburst, as reported by M. Simonsen on October 31. The magnitude (14.4mag) may suggest a superoutburst. No definite superoutburst has been reported since 2000 July (vsnet-campaign-dn 2952). The likely superoutburst is now ongoing (vsnet-campaign-dn 2966). CW Mon (RA = 06h36m54s.5, Dec = +00d02'16") The SS Cyg-type dwarf nova CW Mon experienced a relatively rare full outburst (12.9mag), as reported by D. Taylor on October 29 and M. Simonsen on October 31. The object may be a grazing eclipser with a period of 0.1762 d (vsnet-campaign-dn 2953). (continuous targets) V4744 Sgr = Nova in Sgr No. 4 (RA = 17h47m21s.724, Dec = -23d28'22".79) This nova in Sgr has been given the permanent GCVS designation, V4744 Sgr (vsnet-campaign-nova 1129). In the spectrum taken by M. Fujii on October 29, a weak and narrow H-alpha emission line, associated with a prominent P Cyg profile, has been detected. The NaD absorption line is strong. M. Fujii comments that the overall appearance of the spectrum resembles those of V838 Mon taken around 2002 Feb. to Mar. (vsnet-campaign-nova 1131). H. Yamaoka performed astrometry using images taken by S. Kiyota and P. Nelson and reported the position above. Even in the deepest DSS image (limiting Rmag about 21.0) and 2MASS infrared image, no object can be found within 5" of this position (vsnet-campaign-nova 1137, 1138). Tha lack of a bright 2MASS counterpart seems to preclude the possibility of a symbiotic nova (vsnet-campaign-nova 1139). The object is now V~11 (vsnet-campaign-nova 1123, 1124, 1126, 1127, 1128, 1130, 1132, 1133, 1134, 1136). SN 2002hb (RA = 22h56m03s.58, Dec = +13d37'31".0) According to IAUC 8002, it is a type Ia SN about 1 month after maximum, at a redshift of about 0.09 (vsnet-campaign-sn 488). SN 2002hd (RA = 08h54m03s.39, Dec = -07d11'21".5) According to IAUC 8002, it is also a type Ia SN, about 5 days after maximum at redshift of about 0.035. The discovery magnitude is consistent with the expected maximum (vsnet-campaign-sn 488). SN 2002he (RA = 08h19m58s.83, Dec = +62d49'13".2) According to IAUC 8004, it is SN Ia (possibly subluminous) near or a few days before the maximum light on Oct. 30.47 (vsnet-campaign-sn 490). B. Romanishin commented that this SN is of particular interest because it may be a sub-luminous Ia, and it would be very nice to pin down peak magnitude (vsnet-campaign-sn 492). SW UMa (RA = 08h36m42s.80, Dec = +53d28'38".2) The light curve taken by K. Torii on October 27 shows the fully grown superhumps (0.2 mag)(vsnet-campaign-dn 2937, 2940). L. Kral reported that T. Hynek also confirmed superhumps of 0.2mag on October 26/27 (vsnet-campaign 1346). On October 28, superhumps observed by K. Tanabe further increased in amplitude (0.25mag) (vsnet-campaign-dn 2943). The Oct. 29 data show the presence of (super)QPOs with a typical period of 3-4 min, although the phenomenon is not as striking as in the 1992 one (vsnet-campaign-dn 2957). The superoutburst is still ongoing (vsnet-campaign-dn 2945, 2948). V844 Her (RA = 16h25m01s.69, Dec = +39d09'25".9) V844 Her was reported to be still active at 14.2 mag on Oct. 28 (vsnet-campaign-dn 2942). RR Tau (RA = 05h39m30s.53, Dec = +26d22'26".3) The object is fading since October 18 (vsnet-campaign-orion 36). MisV1181 (RA = 22h58m09s.12, Dec = +66d21'12".4) M. Collins reported negative observations with limit of 13.0mag on 2001 June 28 and October 8 (vsnet-campaign-nova 1135). MisV1147 (RA = 22h54m03s.78, Dec = +58d54'02".1) The object again became fainter than 13.4mag since October 20. T. Kato suspects that there may be a quasi-cycle of 30-40 d (vsnet-campaign-unknown 120). It further faded to <14.7mag on October 29 (vsnet-campaign-unknown 121). The faint state continues (vsnet-campaign-unknown 122). AG Dra (RA = 16h01m40s.98, Dec = +66d48'10".3) The object is now slowly fading (vsnet-campaign-symbio 39). NSV 10934 (RA = 18h40m52s.26, Dec = -83d43'10".24) An outburst of 12.9mag was reported bu R. Stubbings on October 28 (vsnet-campaign-dn 2934, 2939). IX Dra (RA = 18h12m32s.2, Dec = +67d04'41") The object entered a rapid fading phase from the superoutburst around October 30 (vsnet-campaign-dn 2935, 2944, 2947). IP Peg (RA = 23h23m08s.7, Dec = +18d24'59".1) The profile of the eclipse observed by K. Torii and the Kyoto team is unusually deep for the eclipses during outbursts (vsnet-campaign-dn 2936). The object hsa faded (vsnet-campaign-dn 2941, 2968). Z UMi (RA = 15h02m01s.35, Dec = +83d03'48".7) The object further faded. Some observations showed it to be in 12th mag (vsnet-campaign-rcb 82). Z And (RA = 23h33m40s.02, Dec = +48d49'06".1) The object further brightened (vsnet-campaign-symbio 40). BL Lac (RA = 22h02m42s.86, Dec = +42d16'37".6) The object slightly faded in the end of October, however still very active (vsnet-campaign-blazar 281, 282, 283). KK Tel (RA = 20h28m38s.46, Dec = -52d18'45".6) An outburst of 14.4mag was detected by R. Stubbings on October 28. It may be a normal outburst of this new SU UMa-type star (vsnet-campaign-dn 2938). *** Future schedule *** International Workshop -- Extremely High Energy Cosmic Rays -- November 5-6, 2002 at RIKEN (The Institute of Physics and Chemical Research), Japan Suzuki Umetaro Hall (#52), South Area, Wako main campus Contact to: workshop2002@euso.riken.go.jp [vsnet-campaign-grb 8] IAU Colloquium 194 "Compact Binaries in the Galaxy and Beyond" 17-22 November 2003, La Paz, Mexico Contact Details Web page: http://bufadora.astrosen.unam.mx/~iau194 Email: iau194@astrosen.unam.mx [vsnet-campaign-sn 467] [vsnet-campaign-xray 154] Texas in Tuscany XXI Symposium on Relativistic Astrophysics Florence, Italy, December 9-13, 2002 For more information: http://vsnet.arcetri.astro.it/~texaflor/ [vsnet-campaign-xray 142] SUPERNOVAE (10 YEARS OF SN1993J) 22-26 April 2003, Valencia, Spain Web site: http://vsnet.uv.es/2003supernovae/ [vsnet-campaign-sn 342] [vsnet-campaign-sn 452] *** General information *** Nova Sgr No. 4 CCD image taken by S.
