V844 Her: superhumps (de Miguel)
The object has apparently returned to a "frequently superoutbursting"
state (as in 2002-2003).
===
Comments: Clear skies. Object low in the W horizon. Run extended
up to relatively high airmass (X=2.32). After linear
detrending of the data, P_sh=0.0529 d (using ANOVA).
This is to be taken as a very crude estimate of P_sh
as the run only spans ~90 min. The peak-to-peak modulation
is ~0.15. This seems to confirm the superoutburst state
of this object as suggested by visual estimates reported
by P. Schmeer in [vsnet-alert 12307].
<Var-Comp> = 1.00(4)
<Var-Check> = -0.17(5)
<Comp-Check> = -1.172(17)
Using my transformation relations to the V band,
the mean brightness in V is 13.05(4).
