V551 Sgr OUTBURST 2003 September

Time Serie 2003 09 23 Light Curve SSO

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) (Taichi Kato comments)
