[Aavso-photometry] Var Her 04 Update: Not much going on...

[Aaron Price]

Type still unknown...
 It seems Var Her 04 has settled down. No rebrightenings or echo outbursts
have been detected to date. This could turn out to be a UGSU instead of
the more rare UGWZ. It may be time to mine the databases for evidence of
past outbursts. ASAS shows no outbursts from HJD 2452728 to 2453171.7
(when it detects the current outburst). That would make the outburst
interval long for a UGSU, but not unheard of. NSVS has no record of the
star during observations from MJD 2451274 to 2451627

Them thar disappearing humps...
 I've looked a little more closely at the data around 2453187.5 where we
suggested superhumps dissapeared. It seems the 0.029d period reported may
not be reliable. The power of the signal is weak and folding the data
doesn't show a real period there. However, the hump period of 0.058d is
definitely gone from ...187.5 - 188. This could be the quenching of the
outburst. But I caution much more analysis (and time) is needed.

Period evolution...
 I put online a quick and dirty wavelet analysis of our data which shows
the dominant 0.058 period dying around ...187. It can be viewed here:

 I also did a quick and dirty fourier analysis of each day's data
separated into bins. An animated GIF shows the changing period (along with
aliases and some unknown behavior) here:

 All images and light curves have been updated and are available here:

 At this point I'd recommend continued monitoring. Try to get at least 3
hours if possible so we can see if the period returns. If you detect any
activity continue to monitor as long as possible and notify the discussion
group ASAP.
