[Aavso-photometry] HMXB Campaign Time - Lets Go Photon Hunting

[Thom Gandet]

What are the (known?) orbital period and amplitude for V420 Aur?
This star has been on my Be-star monitoring program for several
years, but I have no observations of it yet as that program was
put aside for other things.  If the period is short enough, though, I
may cover some of the light curve at least.  Thanks and good
luck!

Cheers,
