Stefano Valenti (UC Davis), Sheng Yang (INAF-OAPd, UC Davis), David Sand
(UA), Leonardo Tartaglia (UA, UC Davis), Enrico Cappellaro(INAF-OAPd),
Dan Reichart, Josh Haislip, Vladimir Kouprianov (UNC) report on behalf
of the Gravitational Wave Follow-Up by DLT40.
We continued to monitor DLT17ck/SSS17a (GCN 21529;GCN21530; GCN21531),
the electromagnetic counterpart candidate of the LIGO/Virgo GW G298048
(GCN21509).
Following the optical observations reported for DLT17ck/SSS17a
(GCN21579; GCN21531; GCN21567; GCN21541; GCN21590; GCN21553; GCN21560;
GCN21584; GCN21580; GCN21583; GCN21590; GCN21595; GCN21597), here we
report that DLT17ck/SSS17a is continuing fading.
Using data from the PROMPT 5 0.41m telescope located at CTIO, DLT40
observation began at 2017 August 19.99 UT and shows the source at
magnitude r = 18.96 �� 0.10 mag. We also observed DLT17ck in i and z, for
which analysis is under way.
