(ESO) report/s the discovery of a new astronomical transient.

IAU Designation: SN 2022pv; Discoverer internal name: ATLAS22boa

Coordinates (J2000): 
RA = 14:25:08.772 (216.286551667) DEC = -13:09:26.73 (-13.157425)
Discovery date: 2022-01-13 15:20:09.600 (JD=2459593.139)

Photometry SN2022pv; Discovery 2022-01-13 15:20:09.600
Flux: 19.165 ABMag; Filter: orange-ATLAS; Instrument: ATLAS-02
Telescope: ATLAS Haleakala

Last non-detection: Last non-detection date: 2022-01-09 14:49:55
Limiting flux: 19.19 ABMag; Filter: orange-ATLAS
Telescope: ATLAS Haleakala

Likely type SN II

Also in NGC 5605: SN2022 BN type 1b mag 20; SN 2022EC type II mag 18

Editor: Given the likely supernova occurrence per galaxy is about one per
century, having three supernovae simultaneously in NGC 5605 is quite rare.
