report: 
We have undertaken the review of the sky area in vicinity of 
GRB 120311A (M.R. Goad et al. GCN Circ.13035) on 
astronegatives, collected in Ukrainian NAS Main astronomical 
observatory plate archive (1976-1996). All the plates with 
the possible object appearance are digitized using Microtek 
ScanMaker 9800XL TMA and Epson Expression 10000XL flatbed 
scanners and have been placed into Golosiiv Plate Archive 
database DBGPA with open access to them.
 	The list of plates is given in the table:
