GRB100302A : LOAO observations and Lulin afterglow analysis
K.Y. Huang (ASIAA), Myungshin Im (CEOU/Seoul National Univ) and
Y. Urata (NCU) on behalf of EAFON team :
We observed GRB100302A afterglow position (Goad et al. GCN 10460,
Huang et al. GCN 10461 and Cucchiarar & Fox GCN 10465) in i-band
(12x300s) using 1.0 telescope at Mt. Lemmon (Arizona, US) operated by
the Korea Astronomy Space Science Institute.
No significant detection of afterglow in our i-band combined image at
11.0709 hours after the burst. The 3-sigma limiting magnitude is 20.8,
which calibrated with five nearby USNOB stars.
We also reduced R and i band images taken by Lulin 1-m telescopes. Our
photometric results, combined with the i-band detection reported by
Cucchiarar & Fox (GCN 10465), indicate the i-band power law index is
about -0.65.
