V844 Her = Var43 Her [UGSU, 12.5p - 17.5p]
==========================================
Tonny Vanmunster, CBA Belgium reports : "We obtained 4.1 hours of
unfiltered CCD photometry of V844 Her (Var43 Her) at CBA Belgium, on
997, May 23/24, using a 0.25-m SCT and ST-7 CCD. The light curve
clearly shows the existence of prominent superhumps with a semi-
amplitude of 0.18 mag. A preliminary period analysis, using the PDM
method, yields the following best estimate of the superhump period :
0.056d +/- 0.001d. This is among the shortest superhump periods
currently known !
