GRB 101225A, the review of the sky area in plate archives 
V.V. Golovnya, L.M. Kizyun, L.K. Pakuliak (Main Astro Obs, Kyiv) 
report: 

We have undertaken the review of the sky area of GRB 101225A  
(P.A. Evans et al., GCN 11497) 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 flatbed scanner 
and have been placed into Golosiiv Plate Archive database DBGPA  
with open access to them. No any object has been found in the 
point with the mentioned coordinates of GRB.

The list of plates is given in the table:
