Leicester) report:\n\n\"In addition to the spectroscopic observations reported in GCN #11538 we\nalso obtained i-band imaging of the afterglow candidate of GRB 110106B found\nwith the WHT (GCN #11534) with Gemini-N / GMOS.  A total of 900 sec were\nobtained on source at a mean epoch of 2011 Jan 7.347 UT (10.89 hours after\nthe burst and 7.64 hours after the WHT observation).  Digital image\nsubtraction of the Gemini and WHT observations reveals a fading source\nlocated at (J2000):\n\nRA = 08:56:37.267\nDEC = +47:00:10.49\n\nwith an uncertainty of about 0.2\" in each coordinate.  This position is\nabout 1.5\" due east of the galaxy noted in GCN #11534, whose redshift is\n0.618 (GCN #11538).  At this redshift the corresponding projected offset is\nabout 10 kpc.  We note that emission is still detected at the position of\nthe afterglow, indicating that an association with an underlying host\nunrelated to the nearby galaxy may still be possible.\"",
