VSNET Weekly Campaign Summary *** Last week news *** (new targets) V982 Oph (RA = 17h52m37s.86, Dec = +07d32'52".4) According to IBVS 5302, V982 Oph is shown to be a dwarf nova (Antipin and Samus). Please monitor this object, and make time-series photometry when a new outburst is detected (vsnet-campaign-dn 2741). New radio-selected CV in Sextans H. Bond reported: During the FIRST ("Faint Images of the Radio Sky at Twenty Centimeters") 1.4 GHz radio survey, using the Very Large Array, the radio source FIRST J102347.6+003841 has been identified with a previously unknown 17th-mag Galactic cataclysmic variable (CV). Spectroscopic observations suggest that the CV is a DQ Her- or AM Her-type magnetic CV, as are the handful of other CVs that are known to be radio sources. CCD photometry obtained at Kitt Peak shows rapid flickering and slower variations with a peak-to-peak amplitude of at least 1 mag, but has not as yet revealed the orbital period (vsnet-campaign-polar 8). WR104 (RA = 18h02m04s.0, Dec = -23d37'41") The object is gradually brightening. K. Haseda reported 12.3p and 12.2p mag on August 9 and 13, respectively (vsnet-campaign-wr 2). SN 2002eo (RA = 01h52m55s.18, Dec = +36d03'22".2) The LOTOSS team discovered SN 2002eo on images taken on August 20 when it was 18.0mag. NGC 710, the host galaxy of SN 2002eo, is a disturbed spiral galaxy. The expected maximum for typical SN Ia is mag about 16.5 (vsnet-campaign-sn 465). V425 Cas (RA = 23h03m38s.60, Dec = +53d17'10".8 ) Observations by T. Kinnunen show variations between 15.6:-14.6 mag in this ~20 days (vsnet-campaign-nl 96). (continuous targets) TK5 (RA = 19h17m26s.5, Dec = +37d10'41") The object experienced an outburst (14.7mag on August 19 by T. Kinnunen) (vsnet-campaign-dn 2743). WR106 (RA = 18h04m43s.5, Dec = -21d09'29") K. Haseda reported a minor fading (<12.6p mag) on August 5 (vsnet-campaign-wr 3). BX Mon (RA = 07h25m22s.7, Dec = -03d35'50") A brightening to 9th mag was reported. The present level of brightness was last recorded in 1999 (vsnet-campaign-symbio 25, 26). V1504 Cyg (RA = 19h28m55.87s, Dec = +43d05'39".9) The object has faded from the superoutburst (vsnet-campaign-dn 2728). Z UMi (RA = 15h02m01s.35, Dec = +83d03'48".7) No large variation has been reported (vsnet-campaign-rcb 65). BF Ara (RA = 17h38m10s.40, Dec = -47d10'43".4) The superoutburst is still ongoing (vsnet-campaign-dn 2735, 2745, 2748). T. Kato reported that combined light curves obtained by G. Bolt and P. Nelson yielded a superhump period of 0.0881 d, which is slightly longer than the single-night determination. It may be possible that BF Ara experienced a stage of rapid period evolution (vsnet-campaign-dn 2736, 2738). With a new data set on August 21 by G. Bolt, T. Kato reported a revised superhump period of 0.08805(2) d. The mean fading rate during the present superoutburst plateau is 0.08 mag/d, which is relatively small among SU UMa-type dward novae (vsnet-campaign-dn 2739). The profile of superhumps on August 23 has become more symmetric than before (vsnet-campaign-dn 2747). AH Her (RA = 16h44m09s.99, Dec = +25d15'02".1) The object entered a standstill at about 12.5mag (vsnet-campaign-dn 2731, 2744, 2750). ES Aql (RA = 19h32m21s.58, Dec = -00d11'31".2) The slow fading continues (vsnet-campaign-rcb 61). DH Aql (RA = 19h26m12s.05, Dec = -10d15'21".4) The object has faded, and no rebrightening was observed (vsnet-campaign-dn 2737). delta Sco (RA = 16h00m19s.9, Dec = -22d37'17") D. West reported that the spectrum on 08/15/02 shows the H alpha emission feature (vsnet-campaign-be 199). V803 Cen (RA = 13h23m44.5s, Dec = -41d44'30".1) A bright outburst to 12.5mag was detected by R. Stubbings on August 21 (vsnet-campaign-dn 2742). The object was still bright on August 24 and 25 (vsnet-campaign-dnn 2746, 2749). DY Per (RA = 02h35m17s.12, Dec = +56d08'44".7) The object is now gradually brightening (vsnet-campaign-rcb 64). IX Dra (RA = 18h12m32s.2, Dec = +67d04'41") The bright state is reported to continue since August 12. It may be a superoutburst (vsnet-campaign-dn 2740). MV Lyr (RA = 19h07m15s.93, Dec = +44d01'10".7) The faint state continues (vsnet-campaign-nl 95). V838 Mon (RA = 07h04m04s.816, Dec = -03d50'50".94) S. Kiyota reported 10.66C mag on August 20 (vsnet-campaign-v838mon 374). V348 Sgr (RA = 18h40m19s.94, Dec = -22d54'29".1) The bright state continues (vsnet-campaign-rcb 63). omicron Cet (RA = 02h19m20s.67, Dec = -02d58'27".1) The object is now around maximum (vsnet-campaign-mira 31). *** Future schedule *** International Workshop HIGH RESOLUTION X-RAY SPECTROSCOPY with XMM-NEWTON and CHANDRA 24th and 25th October 2002 For more details, visit the workshop website: http://vsnet.mssl.ucl.ac.uk/~gbr/rgs_workshop/ [vsnet-campaign-xray 152] ===== International Symposium ====== "The Universe Viewed in Gamma-rays --- Univ.
