[Aavso-photometry] VV Pup 'flares'

[bedient at hawaii.rr.com]

Just a quickie since I'm at work, but reading some papers in ADS, particularly:
http://adsbit.harvard.edu/cgi-bin/nph-iarticle_query?1972MNRAS.156..305W
I think what I observed on the 17th (the steep decline at the beginning of my observations) was an eclipse of the hotspot by the secondary.  Compare my lightcurve from that night with that in the paper.

VV Pup has a very bright and active hotspot, and I think that's what we have been seeing.

This is cool.  Could turn me into another CV junkie.
