PNV J17275000-1757050   2016 06 07.618 *  17 27 50.00 -17 57 05.0   9.3 U             Oph       0 2

Discovered by T. Kobayashi, Fukui-ken, Japan, on four frames using Sony Alpha digital camera + 80-mm f/2.0 lens, who writes nothing is visible at this location on two night frames taken on 2016 May 27 and June 2 (same instrument, limiting mag.= 12.5). But he found a star (mag.= 9.4) on four frames taken on 2016 June 5.604 UT with 85-mm f/1.4 lens.

Object is minor planet (8) Flora.

2016 06 07.618

Precise position of 17 27 51.37, -17 56 04.6 was measured from a discovery image (but not Good for measurement). On the other hand, (8) is then located at 17 25 37.36, -17 57 49.5 with the residuals of +0.53 and +0.03 deg. So that this PN is not identical with (8).

Quotes: "But he found a star (mag.= 9.4) on four frames taken on 2016 June 5.604 UT with 85-mm f/1.4 lens." and "Precise position of 17 27 51.37, -17 56 04.6 was measured from a discovery image" --- (8) Flora (9.4 mag) was at exactly this position on 2016 June 5.594 UT, so the "star (mag.= 9.4)" was probably the minor planet. However, (8) Flora was indeed 0.5 deg west of the two reported positions on 2016 June 7.618 UT. --- Patrick Schmeer (Bischmisheim, Germany)

2016 06 08.354

No object visible on 6 images taken with DSLR + 50 mm f/1.0 lens taken on 2016 June 08.354, limiting magnitude 11.0. No object seen on the previous night 2016 June 07.368 on 6 images taken with same instrument limiting magnitude 10.8 John Seach, Chatsworth Island, NSW, Australia.

My photometry results should be 11.42 and 10.00 in Rc and Ic. Sorry. Seiichiro Kiyota (Kamagaya, Japan)

my report above actually refers to PNV J17381927-3725077 and not to PNV J17275000-1757050. Sorry. Thank you P. Schmeer for you comment. Seiichiro Kiyota
