TITLE: GCN CIRCULAR NUMBER: 18347 SUBJECT: LIGO/Virgo G184098: La Silla - QUEST Followup DATE: 15/09/20 02:19:15 GMT FROM: David Rabinowitz at Yale U D. Rabinowitz, C. Baltay, N. Ellman (Yale), P. Nugent (LBNL) The La Silla-QUEST survey operating the 10-sq-deg QUEST camera on the 1.0m ESO Schmidt at La Silla, Chile covered the following ~40 sq. deg area overlapping the southern portion of the ~90% confidence area of LVC event G184098 : RA 92.043 to 115.39 deg; Dec -71.053 to -66.261 deg 3 transients were detected with high confidence: LSQ Desig V-mag hh:mm:ss dd:mm:ss ______________________________________________ LSQ15bbj 19.8 07:16:14.45 -69:36:00.36 LSQ15bbc 19.5 07:06:16.63 -67:12:12.24 LSQ15bbb 17.4 07:25:16.51 -69:04:01.20 LSQ15bbb appears to be a supernova 3.1" north-east of 2MASS galaxy J07251616-6904038 at z = 0.037 LSQ15bbc is a likely variable star, with positions appearing in USNO, WISE, and GALEX catalogs LSQ15bbj appears to be a supernova ~3" north of the core of an uncatalogued galaxy The QUEST survey will continue to take nightly observations of the target area described above.
