AAVSO Special Notice #111

Possible superoutburst of DH Aql
June 4, 2008

Further to AAVSO Alert Notice #379, observations of the
dwarf nova DH Aquilae are requested in support of Spitzer
Space Telescope observations.  This object may be 
undergoing a superoutburst at this time, and may therefore
be a candidate for the observations described in the
Alert Notice.  Observers are asked to observe this object
over the next several days to determine whether it is in
fact undergoing a superoutburst.  The most recently reported 
observation puts DH Aql at magnitude 12.6 on JD 2454620.91389
(2008 Jun 03.4139 UT).


DH Aql is located at RA: 19 26 10.80 , Dec: -10 15 29.0 (J2000).
