Short outburst again? ----- DO Dra

*** Last week news ***

(new targets) 
  DO Dra                (RA = 11h43m38s.5, Dec = +71d41'19".1)

    J. Ripero reported an outburst of DO Dra on Feb. 5 at 11.7mag 
  (vsnet-alert 8839).  P.A. Dubovsky and M. Linnolt confirmed the
  outburst on Feb 6 at 11.3mag and 11.1mag, respectively.  This is 
  an intermediate polar, and its outbursts have been very short 
  (vsnet-alert 8840, 8842). 


  OU Vir                (RA = 14h35m00s.14, Dec = -00d46'07".0)

    D. Nogami forwarded a discovery of a rare outburst of OU Vir 
  by T.L. Gomez on Feb 6 (V=15.62) reported to CVNet.  The last
  outburst was in 2004 Jun.  This is an eclipsing SU UMa-type dwarf
  nova (vsnet-alert 8845).  Using the light curve taken by S. Kiyota
  on Feb 7, D. Nogami reported a detection of superhumps, which
  revealed that the current outburst is a superoutburst.  D. Nogami
  commented that the object experienced atypically long rebrightening
  just after the superoutburst of 2003 (vsnet-alert 8848, 8849).

 
  1RXS_J053234.9+624755 (RA = 05h32m33s.87, Dec = +62d47'52".1)

    J. Shears found an outburst of this SU UMa-type dwarf nova on
  Feb 7 (12.3mag), which was reported to CVNet.  The last outburst was
  reported on Oct 3 (vsnet-alert 8847).


  GSC 04370-0026        (RA = 06h25m58s.2, Dec = +73d31'15".4)

    I. Andronov et al. reported the orbital period of the EW-type
  variable, GSC 04370-0026, located near the intermediate polar RXS
  J062518.2+733433.  The period is calculated to be 0.4426426(8) d 
  (vsnet-campaign 1643).


(old targets)
  ASAS 102522-1542.4    (RA = 10h25m22s.23, Dec = -15d42'21".5)

    The object is still in superoutburst, showing large superhumps
  (vsnet-alert 8836, 8833). H. Maehara revised the early superhump
  period to be 0.06157(6) d using the data on Jan 27 and 28.  On the
  other hand, the superhump period, 0.06333(4) d, is 2.8% longer than
  the early superhump period (vsnet-alert 8843).


  ASAS 023322-1047.0    (RA = 02h33m21s.41, Dec = -10d47'04".09)

    P.C. Sherrod reported possible rapid oscillations in the light
  curve on Jan 31 (vsnet-alert 8835, 8837, 8838).  H. Maehara
  performed a period analysis using all data set obtained by VSOLJ
  members, which yielded the best period of superhumps of 0.06333(4) d
  (vsnet-alert 8844).
