and the GROWTH (Global Relay of Observatories Watching Transients Happen) collaboration.

We obtained a spectrum using the SPRAT spectrograph of the Liverpool Telescope, La Palma on 2017-08-25 at 05:25UT of the CNEOST detected transient GWFUNC17-ure (Xu et al, GCN 21675).

Using SNID we classify the source as a Type Ia supernova at redshift z=0.04 and age +18 days.

Assuming z=0.04, the Si ejecta velocity is ~10,000 km/s.
