[Aavso-photometry] VV Pup

[James Bedient]

Hi -

Trust me, it's real.  ;-)

I added check data and changed the scale a bit so both plots are scaled 
the same.  I used the faint star right next to VV as the check.  I  saw 
the decline on the second night take place, which you can see in the 
four thumbnail images below the light curves - that got my attention 
right away.

Aloha,
