TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4855 SUBJECT: GRB060219: Liverpool Telescope observations DATE: 06/03/09 14:11:34 GMT FROM: Evert Rol at U.Leicester E. Rol (U of Leicester), N. Tanvir (U of Hertsfordshire) and C. Mundell (Liverpool JMU), report on behalf of a larger collaboration: We have observed the X-ray position of GRB060219 (Moretti, GCN4788, GCN4797) with the 2m Liverpool Telescope, on two nights in r'- and i'-bands. Within the images, we detect the SDSS-source mentioned by Moretti (GCN4801). In the first epoch r'-band, a very faint source just outside the XRT error circle can be seen as well, with r' ~ 23.4. Image subtraction of the r'-band images between the two epochs shows no variability of the galaxy. The faint source is not visible on the second epoch image, but the second observation is slightly shallower than the first observation, and its estimated source magnitude is around the limiting magnitude of that image. The defringed i'-band images unfortunately suffer from residual fringing and could therefore not be used for image subtraction. No sign of the faint source is seen in these images. Our 3-sigma limiting magnitudes, measured in a aperture equal to 1 times the estimated seeing, and calibrated to the SDDS-r' and i' magnitudes, are as follows: time filter limiting (days post trigger) magnitude 0.220 r' 23.7 4.15 r' 23.5 0.276 i' 22.9 4.17 i' 22.6 We note that the galaxy inside the XRT error circle appears to have slightly different magnitudes than those quoted by Moretti (GCN4801). According to the SDSS derived model magnitudes (Cool, GCN4789), its magnitudes are u' = 25.105, g' = 22.698, r' = 21.941, i' = 21.153 and z' = 20.491. The r' and i' magnitudes are in agreement with the estimates from our photometry.
