GCN Circular 9197
C. Guidorzi (U. Ferrara), D. Bersier, C.G. Mundell (Liverpool JMU) on behalf of a large collaboration report: Following the distribution of the enhanced Swift-XRT position (Beardmore et al. GCN Circ. 9194) of GRB 090422 (Ukwatta et al. GCN Circ. 9185), we re-analysed the data acquired with the Liverpool Telescope, mentioned in our previous report (Guidorzi et al. GCN Circ. 9187). Inside the enhanced XRT error circle we detect a single object with magnitude of (21.7 +/- 0.3) in the r' filter, from 11 to 43 min post burst, at the following position (J2000): RA= 19:38:59.91 Decl= +40:23:03.5 with an uncertainty of 0.7 arcsec. The calibration was done with respect to nearby USNOB-1 stars, using the R2 magnitudes values. This source is also detected in i' and z' filters. At the moment we cannot assess whether the object is fading. The source of r'~19 mag mentioned in our earlier report lies outside the enhanced XRT error circle. Further observations are planned.
