Dear colleagues!
I would like to send you observations of a new variable star (BeV5), which I have discovered in a systematic CCD-based search for new variables.
Instruments (K.Bernhard):
CCD-camera: Starlight SX
Telescope: Celestron-8 (20 cm Schmidt-Cassegrain)
New variable star:
new BeV5 062040.0 N061608.2 (2000) 11.6 12.1(ccd)
comments:
BeV5: GSC 144 1300
The range of 11.6-12.1 mag and the slow variation of brightness suggests a semiregular variable (SR).
Comparison star is for all following observations of W.Quester (QU.BAV) and K.Bernhard (Be) GSC 144 1333 (12.5 mag), which was prooved to be constant.

The variability of GSC 144 1300 was confirmed by observations of Wolfgang Quester (QU.BAV).
The almost constant difference in the observed brightness of about 0.25 mag between measurements of W.Quester and K.Bernhard can be explained by the use of CCD-cameras with different spectral sensitiveness.
