SN is located at about R.A. = 16h17m58.09s, Decl. = -60o42'41.0" (equinox J2000.0), which is 193" W and 59" S from the nucleus of 2MASX J16180412-6041419 (16h18m04.13s -60o41'41.9"). The PSN is visible on two separate images and may also be hostless The PSN does not appear in an image taken 2016-05-18T04:15:19
