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).
