Kuntal Misra and S. B. Pandey (ARIES NainiTal), on behalf of
larger Indian GRB collaboration
We observed several R_c band frames of the GRB 041006 optical afterglow,
determined the magnitudes in comparison with the stars A and B as reported
in GCN 2792 using 1.04-m telescope of ARIES Nainital India. The OT decayed
by ~ 0.5 mag from Oct 6.75 to Oct 6.91 UT.
Preliminary R_c - band magnitudes are:
Oct 6.776284 19.81 0.05
Oct 6.830509 20.00 0.05
Oct 6.862395 20.02 0.05
Oct 6.877175 20.18 0.06
The temporal flux decay index is ~ -1.0. We did not notice any considerable
steepening in the light curve using our data set.
