We have observed SN2004cs (IAUC 8361 ) in the Johnson BVR and Gunn g bands
with the robotic Palomar 60-inch (1.5-m) telescope + CCD imager.
Data were obtained on June 24 UT, one night after the
discovery report for SN2004cs, and calibrated with images obtained on July 30
UT. The derived magnitudes and uncertainties for SN2004cs on
June 24.3 UT are: B=18.16(0.07) mag, V=18.06(0.07) mag,
R=17.87(0.08) mag and g=18.23(0.05) mag. This combination of B-g
and R-V colors is strongly suggestive of a type Ia identification
for this event (see Gal-Yam et al. 2004, PASP, 116, 597; http://wise-obs.tau.ac.il/~dovip/typing, and references therein).
