larger  collaboration report:

We observed the field of GRB 130427A (Maselli et al., GCN 14448) on Apr. 
28 between (UT) 16:22-18:41 with 22-m radio telescope RT-22 of
Crimean Astrophysical Observatory at mean frequency of 36 GHz. At the 
position of  the optical (Elenin et al., GCN 14450; Perley et al., GCN 
14451) and radio afterglow (Zauderer et al., GCN 14480; Zauderer et al., 
GCN 14482; Perley, GCN 14494) we detected a source with a flux 1.9 ± 0.4 
mJy  at T_mid = 1.405 days after burst trigger.
