MASTER OT J021729.29-595123.9 discovery - PSN in 28.8W" 49.2"S of NGC888

MASTER-SAAO auto-detection system( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 02h 17m 29.29s -59d 51m 23.9s on 2016-08-23.12639 UT.
The OT unfiltered magnitude is 16.1m (mlim=19.1m).
The OT is seen in 2 images at MASTER-SAAO and in 2 images at MASTER-OAFA(2016-08-23 06:25:27UT). We have reference image without OT on 2015-10-05.07014 UT with unfiltered magnitude limit 20.5m and on 2016-08-12 09:37:50UT with m_lim=20.6 at MASTER-OAFA.
This PSN is in 28.8W" 49.2"S of the center of NGC888. Spectral observations are required.
