Continuing our efforts (LVC GCN 20981, 21804) to detect radio emission from
SSS17a (Coulter et al. LVC GCN  21529) on milliarcsecond scales, we observed
the transient at 5 GHz with the European VLBI Network between 10:00���14:30 UT
on 20 September 2017. The 5 sigma upper limit around the HST/Gaia position
(Adams, Kasliwal & Blagorodnova, LVC GCN 21816) is 140 microJy/beam.
Further observations are planned.
