8.ADDITIONAL COMMENTS:
	Video evaluation accomblished with VirtualDub1.6.14
        No occultation detected, but it is possible that a positive
        occultation on my position was missed due to clouds.

        Target star TYC 6254-00398-1u, +10.8mag, 19deg Elevation

        Only Clear glass filter (Astronomik) for CCD protection was used

        Integration time was changed from 160ms to 2.56s due to changing clouds
