AT2018aoy - scoperta nuova probabile Supernova in IC1069
Inviato: 3 apr 2018, 1:13
Dopo un lungo periodo di forzato riposo (causa meteo) all'alba di Pasquetta pare abbia scoperto un nuovo transiente nella galassia IC1069 di ca. 18 mag.
Stavolta il segnale non era proprio debole ed essendo la galassia circumpolare, ho preferito inserire da subito il report nel TNS, senza attendere alcuna immagine di conferma (lo so, loso, non si fa! ) che invece ho ottenuto solo ora...

Discovery
M.Caimmi report the discovery of an apparent supernova on image obtained at 2018 04 02.15958 with SC Telescope 0.24-m f/6.5 and CCD Atik 314L (exp 15 frame x 30sec) from Valdicerro Observatory (C92) - Loreto (AN) Italy, during the Italian Supernovae Search Project (ISSP). The new object is located at A.R. = 14h50m47s.92 Decl. = +54°24'28".8, show the source at 18.0 Mag. Astrometry with respect to UCAC-4 stars which is 12" South and 12" Est from the centre of Galaxy IC 1069 (PGC53000).
Follow-up
This transient was observed on 2018 04 02.86324 by M.Caimmi from C92 - Valdicerro Observatory, Loreto (AN) Italy using 0.24-m f/6.5 SCT + CCD Atik 314L in the course Italian Supernovae Search Project (ISSP). Stack of 30 unfiltered b2x2 frames x 60sec guided exposures, show the source increase at 17.6 Mag. End figures for astrometry were AR. 47.85s DEC. 29.0" position measured from UCAC-4 reference stars catalogue.
Questa sera la luminosità sembrava essere aumentata alla 17.6 mag... e adesso aspettiamo la conferma spettroscopica!
