Na začátku chvíli přecházely mraky, během pozorování na chvilku zazlobila pointace, na konci bylo svítání - všechny vadné snímky jsem vyřadil. Obloha slušná, mírný opar, mírný vánek. FWHM 6-7, expozice 60 s. TminHJD = 2455710.53447 +/- 0.00310 DQ = 5. Sice se mi daří zmenšovat chybu měření poklesu, ale hodnocení křivek mám pořád horší a horší :-(
