We conducted a total of 22 e-MERLIN observations of SSS17a (Coulter et
al. LVC GCN 21529) from Aug 23 to Sep 22, 2017 for about 5 hours per
run. The observing frequency was centred at 5 GHz with a bandwidth of
512 MHz. The average synthesized beam size was about 200 mas x 30 mas
at a position angle of about 0 deg. There are no significant
detections in individual runs or in different combinations of adjacent
runs coincident with the position of the transient.
The 3-sigma upper limits in microJy/beam are listed below (first six
runs were already reported in LVC GCN 21804). UTC date and times refer
to the middle of the experiments:

Additional observations are planned with e-MERLIN to continue the
monitoring of the transient source.
