We detected the candidate couterpart of iPTF13ecv (Singer et al, GCN 15524) at the following position (+/- 1 arcsec), mag 18.8 +/-0.2: RA (J2000.0) = 20h 31m 47.79s DEC(J2000.0) = +00d 59m 22.8s We imaged again (for 5 days after) the field of iPTF13ecv optical afterglow candidate of GRB 131127B (Leo Singer: GCN 15524) with the robotic telescope of (IAU station 565) Bassano Bresciano Observatory, Italy (member of ISSP:Italian Supernovae Search Project). We have observed that the brightness of this object is not decreased during 5 days after the discovery. Magnitudes were estimated with the USNO-B1 cat.
