Shot from Comana, Giurgiu, Romania, with the Moon at 88%

This transient was observed on 2019 02 15.05877 by M.Caimmi from C92 - Valdicerro Observatory, Loreto (AN) Italy using 0.24-m f/6.5 SCT + CCD Atik 314L in the course Italian Supernovae Search Project (ISSP). Stack of 15 unfiltered b2x2 frames x 30sec unguided exposures, show the source at 17.1 Mag. End figures for astrometry were AR. 42.45s DEC.16.7" position measured from UCAC-4 reference stars catalogue.

Magnitude: undetermined, as a means of brightness comparison the following image showing the area of the AT (yellowish spot on the left) and to the right another yellowish object of slightly more brightness.
The pixel scale is 1:1

Confirmation date: Feb.6th, 2019
Frame exposure date: Feb.6th, 2019, 00:30 a.m. MEZ (UTC+1)
OTA: 10"RC f/8
Camera: Canon Eos800Da
Stack of 7 Frames with 180sec exposure time @ISO400 (pure lights only, no darks, no flats, no bias)
Colours: only saturation enhanced, no colour shift or other colour treatment
Magnitude: undetermined, as a means of brightness comparison I zoomed into the area showing the AT (yellowish spot on the left) and to the right another yellowish object of slightly more brightness.
Seems like only 1 image per post, so the zoom-in image will follow in the next post...

Vîntdevară Dumitru Ciprian, I confirmation of an apparent transient in M 51, RA = 13 29 42,45 DE = +47 11 15,1 (mag. 17.3) on unfiltered CCD frames, taken with a 0.2-m reflector on in Bârlad Observatory, Bârlad, Vaslui, România.
