J.W. Lee, J. Yoon, S.-L. Kim, C.-U. Lee (KASI), on behalf of EAFON team.
We took R-band images of GRB080330 (Hao et al. GCN 7537)
using the 1.0m telescope at Mt. Lemmon (Arizona, US)
operated by the Korea Astronomy Space Science Institute.
The R-band imaging started at March 30, 06:57:55.1 UT
(3:15:56 after the burst).
We clearly detect the afterglow at the location reported by
Schaefer et al. (GCN 7538).

-------------------------------------------------------------
06:57:55.1 07:11:50.4 19.63 +- 0.05
(3hr15m after burst) (3hr30m after burst)
The magnitude is calibrated with a GSC2.2 star at
(11:16:56.54, +30:37:51.4).
The afterglow faded by more than 2 magnitudes since the
detections shoftly after the burst (GCN 7536, 7538, 7543).
