This star is way out of season, but eclipsing polars are extremely rare 
and valuable - so let's give Arto some fine data!

Hello from freezing cold Finland!

I am looking for another observer for this interesting though quite
challenging target. I have observed three eclipses on three nights and
it looks like the orbital period is 3.8 hours. As the star is rather
low on the evening sky it is difficult to cover two eclipses on single
site, so another observer few hours West from Finland would be very
helpful. If my prediction holds there should be an eclipse tonight at
20:15 UTC. The star is around mag 16 outside the eclipse and invisible
when eclipsed. The eclipse duration is roughly 15 minutes.

best regards,

arto
