D. Kato, T. Nagata, and IRSF/SIRIUS team (Nagoya Univ, NAOJ), N. Kawai
(Tokyo Tech) report:
We have imaged the field of GRB030115 (Kawai et al, GCN 1816) at J, H,
and Ks with the Simultaneous three-color InfraRed Imager for Unbiased
Survey (SIRIUS) on the Nagoya-SAAO 1.4m telescope (IRSF) on 2003 Jan
16.0 UT. At the position of the afterglow candidate suggested by
Levan et al (GCN 1818) and Vrba et al (GCN 1822) we made marginal
detection in these bands, and the preliminary magnitudes are:
J = 20.2 +- 0.3
H = 19.9 +- 0.3
Ks= 18.4 +- 0.3
