NGC 4545 - Spiral Galaxy with Type II Supernova 2022fuc

NGC 4545 with SN2022fuc (Draco) SN 2022fuc (Type: II) discovered 2022-04-02.878 UT by Giancarlo Cortini Alias: ATLAS22lhg, ZTF22aadpuwe Discovery Magnitude 17 ' Past image of the same field taken on 2022/03/03.98 showed nothing at that position (limit mag.+18.5) '  ( Rochester Supernova site | TNS 2022fuc )

NGC 4545 with SN 2022fuc - 2022-05-28 (T+55.2d) Image below (2022-05-28.028) was taken 55.2 days after discovery of 2022fuc Position of SN (faint but distinct) is shown by white cross-hairs Poor quality image (due to pasing cloud/poor sky transparency, some wind shake)

Annotated CCD Image (150% size, square root scale, cropped) 3 x 180s exposure (average combine), 3x3 binning, C Filter 2022-05-28 00:47 UT (#1012029-31) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2
