V551 Sgr: drefinite superoutburst of a new SU UMa star!

Dear Colleagues,

   Roland Santallo (Southern Stars Observatory) has just sent us Sep. 23
observation of V551 Sgr.  The object already showed prominent superhumps
(amplitude about 0.3 mag).  This observation finally confirmed the supposed
SU UMa-type nature of V551 Sgr!  The superhump period is still rather
uncertain (around 0.06 d), but will be readily refined when the baseline
coverage is improved.  Congratulations, Roland -- this observation finally
revealed the long-waited nature of this object, which had been a problem
between us since last glimpsed a short outburst early this year!

Regards,
Taichi Kato
