Jorma Ryske, Etelä-Suomen kosmol. seura

SN2018zd in the galaxy NGC2146, bongaama of Rauno. A total of 15 minutes of exposure. L of the single image taken with the filter measured for the supernova mag 13.92 with FotoDif, which happened to be exactly the same as the magnitude of the reference star GSC0452900535.

Added blinking animation of visible light image and narrowband NUV range 387nm / 15nm image. Blinking shows interesting variations in the brightness of the supernova, different stars, and the galaxy NGC2146 itself. SN2018zd discharges hot, clearly visible on UV, its brightness is already approaching the brightness of the core of its home galaxy. The NUV image is carelessly focused and the full moon twitch spotted the images.
