A possible nova in Scorpius [Nova Sco 2008, V1309 Sco] was posted to the CBAT Unconfirmed Objects list (D. Green, editor); the object was at magnitude 9.5 (C) on 2008 September 02.4594.  The object has not been classified, but the existence of the new source was confirmed by Guido et al.

Pending classification, the AAVSO requests observations of this new object.  Both visual observations and instrumental photometry are strongly encouraged.  An AAVSO Alert Notice will be issued if and when the object is classified as a Nova.  A sequence has not been created specifically for this object, but several comparison stars are available within the field.  Fainter comparison stars will be added when available.

This object is located at the following coordinates from Guido et al. (see vsnet-alert 10490):
