[vsnet-alert 19862] VRI photometry of J16211735+4412541

[Bartek Debski]

Dear all,

Last night I gathered VRI data with our 35-cm Maksutov telescope in
Krakow. Observations covered whole orbital period (0.21 day). Around HJD
2457544.51 there is an 0.9-magnitude deep V-shaped minimum. It seems that
the contact binary hypothesis can be fully discarded.
Reduced, preliminary R-filter lightcurve can be found here:

I am going do a second run today.
