We also observed ASAS 150946-2147.7 on 2009 April 7.28, in B and V filters with
the SMARTS 1.3m telescope at Cerro Tololo.  We verify Henden's results above.

The object appears stellar in B and V, in seeing of about 1".1.  

We will attempt spectroscopic observations with the SMARTS 1.5m over the next
few nights.
