[Aavso-photometry] Newly Observed Eclipsing Variable in Pisces?

[Wolfgang Renz]

Hi Bill, Hi Fred

How accurate are your coordinates ?

If you search for your position in VSX:
http://www.aavso.org/vsx/index.php?view=search.top
you will find 6-10" away an eclipser that would fit well (triple entry of
the same var from different catalogs):

Looking at the DSS images shows that it should be the same star:
