CzeV - The Czech Variable Star Catalogue

We present the first release of the Czech Variable star catalogue that currently contains 1228 stars whose variability was discovered by 60 Czech observers. The catalogue contains confirmed variable stars of various types, but also candidates. We give precise coordinates, cross identification with other catalogues, information about constellation, variability type, brightness, light elements, name of the discoverer and year of discovery. In eighty-eight percent of stars the variability type is estimated, for more than 60 % of the stars the light ephemerides are given.

Observations of possible symbiotic star V335 Vul

We present visual and CCD VRI observations of a suspected symbiotic binary V335 Vul. Long term photometry suggests usual Mira or SRa pulsations. High speed V band CCD photometry didn't reveal anything unusual above 0.02 mag.
