N2 - "We have observed the field of the GRB/XRF 020427 (GCN Circulars 1383, 1384,1386, 1390, 1394) on 11.388-11.397 June 2002 with the 8.2-m VLT telescope at Paranal ESO's observatory (equipped with FORS2). Imagery was obtained in the B- and R-bands (300-s exposure time each) under rather poor seeing conditions (1".2). The position of the likely X-ray afterglow detected by BSAX and followed-up by Chandra (GCN Circulars 1387, 1392) is coincident with the north part of a extended (about 4" x 2"), blue object with R =23.3 +/- 0.2 and B = 23.8 +/- 0.4 which is consistent with the galaxy system reported independently by Fruchter et al. (GCN Circ. 1440). An identification chart is posted at www.iaa.es/~ajct/XRFs/xrf02042
