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).
