   I'm not sure whether dwarf-nova type absorption lines can easily be
detected with this set-up, but this object certainly needs further
follow-up.

We have detected an unresolved optical transient in the Palomar-Quest
(PQ) driftscan   obtained at the Mt. Palomar 48-inch Oschin Schmidt Telescope
on Jan 19 2008 UT:      

PQT 080119:091534+081356  detected at UT 2008-01-19 08:15:43   
J2000 coordinates: RA=09:15:34.91, Dec=08:13:56.1

PQ discovery observations consist of images in Gunn g, r, i, z filters
spanning 10-12 minutes. The transient was confirmed in the second scan
on the same night, and again on the next night (Jan. 20, UT) and had not
faded. The transient matches the location of a r=22.99 mag object in SDSS
images and was approximately r=17.3 when discovered. Spectra of the object
were obtained at Mt. Palomar 200-inch Hale telescope using the Double beam
Spectrograph by G. Herczeg. A preliminary analysis shows a relatively featureless
continuum, with no obvious line emission.  Analysis of the spectra is in
progress.      

We are also in the process of obtaining follow-up photometry at the
Mt. Palomar 60-inch telescope. Further observations are encouraged.
