Likely superoutburst of DH Aql The SU UMa-type dwarf nova DH Aql is presumably undergoing a superoutburst as reported by A. Pearce. The latest reported superoutburst of DH Aql occurred in 1997 May. Although the superhump period of 0.0805 d was determined by Nogami and Kato (IBVS 4227), the accurate determination of the superhump period is still pending further observations. Time-resolved photometry is strongly encouraged during the present bright outburst. YYMMDD(UT) mag observer 990327.891 <147 (A. Pearce) 990329.901 <145 (A. Pearce) 990404.882 <145 (A.
