Pozanenko (IKI) report\non behalf of a larger collaboration:\n\nWe observed the optical transient of XRF 080109/SN 2008D in NGC 2770\n(Berger,  Soderberg, GCN 7159; Deng, Zhu, GCN 7160) on January 11,12,13 with\nCrAO 2.6 telescope  (ZTSh).  On Jan. 11 observations were completed in BVRI\nand on Jan. 12-13 in BR filters under good weather conditions.\n\nPreliminary photometry of the transient XRF 080109/SN 2008D obtained after\ngalaxy subtracion and assuming  reference stars from USNO-A2.0\n1200-06240802,  R=17.3, B=17.7 (the same star used in GCN 7162 (D'Elia et\nal)):\n\nMid time (UT), Filter, magnutude\n\nJan. 12.04 B 18.63\nJan. 12.04 R 17.98\nJan. 13.01 B 18.74\nJan. 12.99 R 18.04\nJan. 13.93 B 18.84\nJan. 14.01 R 17.98\n\nTypical statistical uncertainties of magnitude in the table above is better\nthan 0.01.  Magnitudes are not corrected for Galaxy reddening.\n\nWithin our observations  B magnitude is fading  on Jan. 11-13, while the R\nbrightness has a minimum on the night on Jan. 12/13.  Color (B-R) gradually\nincreasing from 0.65 (Jan. 12) to 0.86 (Jan. 14) which aslo may support of\nSN dominance in light  curve of the transient (Malesani et al. GCN 7184).",
