 New CCD observation of V728 Her shows asymmetric light curve near minimum. There is no asymmetry present in photometric B and V light curve obtained in 1988 by Agerer and col. New multicolor CCD observation of V728 Her is needed.

Simbad object(s): V728 Her,

Dear Mr. Brat.
Is it still possible that the asymetry is caused by chromatic extinction effects ?
Did you check the colors of the comp and check stars ?

Variable and comparison stars have aproximately the same color (according to color-combinated ccd image).
