[Aavso-photometry] Re: [cvnet-discussion] VV is one lonely Pup!

[Arne Henden]

VV Pup is at -19:03, so at 41:45 north it would transit at 29:12 above
the southern horizon.  At 43:47 north, it would transit at 27:10 above
the southern horizon.  The difference is pretty small, and I'd
probably pick your NH observatory.  Sea level observations over the
ocean will have large extinction close to the horizon.  However,
vacationing in Cape Cod with a teaser of some VV Pup observations
would be hard to turn down!
