Targets for observation with the 70cm-telescope
Current target until 2am is Paloma (V 120 sec). The hot object for the remaining part of the night is WX LMi (end of this list) for whose light curves seem to deviate from the known behaviour. Expose this star in the R-band for 30 sec.

If you are observing, please fill out a night report at the end of your observation, regardless of what your target or results are.

If your target is not in the list you can create visibility plots here
(AIP observatory coordinates: 13.106 52.380 62.0)
and finding charts here (for printing download FITS file, open it in ds9 and choose "Color" and "Invert Colormap").
