The transient Gaia14aat was detected by the Gaia Photometric Science Alerts
programme with a magnitude of 15.66 at UT 2014 Oct 10.59. We measured the
object position as RA / DEC = 03:31:4.44 17:25:40.22 (J2000). There is
an object present at this position in the SDSS survey with an r-band magnitude
of 18.93 -/+ 0.15.  

Using the SPRAT spectrograph installed on the 2.0m Liverpool Telescope,
we obtained a 10 minute low resolution (R=350) spectrum of this object
at UT 2014 Oct 15.08, covering the wavelength range 400-790nm. We detect
a bright H-alpha emission line and fainter H-beta and H-gamma emission
lines in the spectrum.
