Nanni (INAF/OAR and Second University of Roma \"Tor Vergata\"),\nI. Bruni, S. Galleti (Bologna Observatory) and G. Pizzichini\n(INAF/IASF Bologna) report:\n\n\"We observed the field of GRB 060526 (Campana et. al., GCN 5162)\nwith the 152 cm Cassini Telescope located in Loiano, equipped\nwith BFOSC in the nights april 26-27 (seeing 2\".0) and 27-28\n(seeing 1\".7).\nThe photometry is based on the SDSS stars (Cool et al. GCN 5164)\nand trasformation derived from Lupton (2005). Using this\ntransformation we find for the USNO B-1 star (RA = 15 31 18.6,\nDE = +00 17 34.9) the magnitude Rc = 16.50, consistent with the \ncalibration of Khamitov et al. (GCN 5177).\n\nWe find the following magnitudes:\n\nMean...UT .......Filter........Exptime (s).......magnitude\nMay...26.908........Rc............900............18.85+/-0.08\nMay...26.921........Rc............900............18.92+/-0.07\nMay...26.935........V............1200............19.37+/-0.08\nMay...26.949........I.............900............18.60+/-0.06\nMay...26.961........Rc............900............19.08+/-0.07\nMay...26.975........V............1200............19.64+/-0.09\nMay...26.990........I.............900............18.80+/-0.06\nMay...27.002........Rc............900............19.28+/-0.09\nMay...27.017........V............1200............19.79+/-0.11\nMay...27.031........I.............900............18.94+/-0.08\nMay...28.002........Rc............900............20.61+/-0.13\nMay...28.017........Rc............900............20.44+/-0.10",
