Dear colleagues, I attach three data files with results of CCD photometry of the amazing WZ Sge obtained at Ostrava observatory (I hope attachments are allowed here). The light curves as GIFs can be found at ada.astronomy.cz or at http://vsnet.sin.cvut.cz/~lkral/wzsge.zip The description of the series follows: wz1.dat - 28th/29th July, observer Marek Kolasa, CCD ST-7 + R filter of RGB set, 5.5 cm photo-lens, exp. 70 s - a whole-night run, nice oscillations with amplitude ~0.3 mag wz2.dat - 30th/31th July, observers Lukas Kral and Marek Kolasa, CCD ST-7 + R filter of RGB set, 5.5 cm photo-lens, exp. 100 s - another whole-night run, the amplitude of the oscillations decreased to ~0.15 mag wz3.dat - 30th/31th July, observer Tomas Hynek, CCD Meade Pictor 416XTE unfiltered, 10 cm telescope, exp. 30 s (technical experiment with Tomas's new camera, shorter run, but in very good agreement with the ST-7 data from the same time) Used comparisons for all runs: - main comparison (C): GSC 1621:1830 - first check star (C1): GSC 1622:989 - second check star (C2): GSC 1621:2233 Aperture photometry was done by Munipack for DOS 2.2 beta2. The format of the data files is briefly described inside of them (geoc. Jul. date, Var.-Comp. mag, standard deviation of measurement etc.) Clear skies!
