TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  1373
SUBJECT: GRB 020409: Optical Observations
DATE:    02/04/15 21:50:03 GMT
FROM:    Daniel E. Reichart at U.Chicago/Astro  <reichart@oddjob.uchicago.edu>

M. Nysewander (U. North Carolina), F. Mullally, S. Salviander, D. Winget (U. Texas), D. Reichart (Caltech), J. C. Clemens, J. Rose (U. North Carolina), J. C. Wheeler, B. Schaefer, and P. Kumar (U. Texas) report:

We observed the central 3.5 arcmin x 3.5 arcmin of the 6.4 arcmin diameter error circle of GRB 020409 (GCN 1347) with the 2.1 m Otto Struve telescope at McDonald Observatory for 2280 seconds on April 10 (beginning 29.3 hours after the burst), and for 1860 seconds on April 11 (beginning 53.1 hours after the burst).  No filter was used.

Visual comparison of the images reveals no transients down to our limiting magnitude, which we estimate to be V ~ 23 mag.  This is consistent with the deeper search of Price et al. (GCN 1368).
