During the on going BOSS sky survey on 2017 March 7th and 8th using data from Parkdale Observatory, Stuart Parker, Canterbury, New Zealand, reports the discovery of 3 apparent supernovae on a 30-s Clear filter CCD image (limiting mag 18) taken by himself with a 30-cm Astro-Tech AT12RC Ritchey-Chretien astrograph (+ ST10 camera) .
AT2017caw RA=08:07:50.10, DEC=-61:46:15.60, Discovery date=2017-03-08.078, Discovery mag=18 Filter:Clear-offset 1.5W 14.6S
AT2017bzc RA=23:16:14.69, DEC=-42:34:10.90, Discovery date=2017-03-07.219, Discovery mag=12.8 Filder:Clear- offset 45E 50N
AT2017bzb RA=22:57:17.30, DEC=-41:00:57.60, Discovery date=2017-03-07.213, Discovery mag=13 Filter: Clear-offset 12W 196N
AT2017bzb and AT2017bzc are very early morning targets being very low just before sunrise. AT2017bzc seem to still be brightening at approximately mag 12.5 clear filter in observations taken on 2017-03-10 6:16UT
