Abstract No optical counterpart has been found for the Soft Gamma Repeater SGR 1806-20 on 1503 archival plates. The implications of this negative result for the burst source are discussed. Also, no time-correlated plate could be found for those of the published gamma-ray bursts that occured at Sonneberg night time and δ>−30°.
