[Aavso-photometry] VAR HER 04 early data results

[Aaron Price]

 The data is coming in hot and heavy now. There are some excellent data
runs and light curves to look at. I updated the light curves on this page
and separated them so the detail can be easily seen:

 Note the zero point differences are likely caused by the lack of filters
being used.  We will take that into consideration when analysing the data.
Note also that almost everyone is reporting at least some sort of
uncertainty/error estimate. Way to go!

 Dr. Peter Garnavich has gratiously shared with us a phased light curve of
about 5 hours of data he took with the 1.8m VATT telescope on June 25. We
have placed it online via the previously mentioned web page.

 A preliminary analysis (ie quick and dirty!) of our data reveals that the
superhump period has increased slightly by about a minute since Lew Cook's
observations about 3 days ago. That is still within the margin of error
(we need more data!) so may be insignificant, or it could be the shift
from orbital humps to superhumps expected at any time.

 Perhaps more significant, the amplitude has dramatically increased from
0.9 to around 1.3 mags (based on eyeball estimate)!

 I hope this weekend brings with it lots of nice and long data sets...
remember quality over quantity for this campaign.
