2004IAUC.8270....2M

W. P. S. Meikle, Imperial College, London; and S. Mattila, Stockholm Observatory, report observations of SN 2004C carried out by D. Carter and R. J. Smith, Liverpool John Moores University, on Jan. 16.2 UT using the Liverpool Telescope (+ RATCam) on La Palma. Preliminary photometry yields the following values: g' = 18.31, r' = 16.74, i' = 16.37, z' = 16.12 (uncertainties about ± 0.05 mag). Comparison of the g'-r' and r'-i' colors with the intrinsic g-r and r-i values for a type-Ic supernova (Poznanski et al. 2002, PASP 114, 833, Fig. 8) at 3 weeks past maximum light (cf. IAUC 8269) indicates an extinction exceeding A_v = 1.0.
