Optical observations of the bright long duration peculiar GRB 021004 afterglow
S. B. Pandey, D. K. Sahu, L. Resmi +9
The CCD magnitudes in Johnson and Cousins and photometric passbands are determined for the bright long duration GRB 021004 afterglow from 2002 October 4 to 16 startin…
Optical and Radio observations of the bright GRB010222 afterglow: evidence for rapid synchrotron cooling?
R. Sagar, C. S. Stalin, D. Bhattacharya +8
We report photometric observations of the optical afterglow of GRB010222 in V,R and I passbands carried out at UPSO, Naini Tal between 22-27 Feb 2001. We determine CCD Johnson BV a…
GRB 000926 and its optical afterglow: Another evidence for non-isotropic emission
R. Sagar, S. B. Pandey, V. Mohan +2
CCD Johnsons BV and Cousins RI photometric magnitudes are determined for 20 stars in the field of GRB 000926. Using them as calibrators, B and R band light curves are constructed o…
Temporal behaviour of emissions from Gamma-ray bursts and optical/near-IR afterglows of GRB 991208 and GRB 991216
R. Sagar, V. Mohan, A. K. Pandey +2
The CCD magnitudes in Cousins R and I photometric passbands are determined for GRB 991216 and GRB 991208 afterglows respectively about 1 and about 3 day after trigger of the corres…
Optical follow up of the GRB 990123 source from UPSO, Nainital
R. Sagar, A. K. Pandey, V. Mohan +4
The CCD magnitudes in Johnson and Cousins photometric passbands are determined for the optical transient of GRB 990123. These observations have been taken approximately 12…
BVRI CCD photometric standards in the field of GRB 990123
Nilakshi, R. K. S. Yadav, V. Mohan +2
The CCD magnitudes in Johnson and Cousins photometric passbands are determined for 18 stars in the field of GRB 990123. These measurements can be used in carrying out pre…
