NGC 6701 - Spiral Galaxy with Transient AT 2022nxe

NGC 6701 with AT 2022nxe (Draco) AT 2022nxe (Type: unk) discovered 2022-06-29.860 UT by Jan Ovidiu Tercu, Gabriel Cristian Neagu  (GLO) ( Galati Astronomical Observatory of the Natural Sciences Museum Complex Galati, Romania ) Discovery magnitude +15.8 (R)  ( TNS 2022nxe )

NGC 6701 with AT 2022nxe - 2022-08-06 (T+37.2d) Image below (2022-08-06.048) was taken 37.2 days after discovery of 2022nxe Position of reported transient (visible ?) is shown by white cross-hairs Measured magnitude ? (unable to determine using SExtractor)

Annotated CCD Image (150% size,  square root scale) 5 x 180s exposure (average combine), 3x3 binning, Clear Filter 2022-08-06 01:18 UT (#1025023-27) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2

NGC 6701 - Reference Image Magenta cross-hairs drawn at the coordinates of AT 2022nxe Apart from the bright arm on the galaxy the reference image doesn't appear to any obvious object at the AT 2022nxe coordinates Transient is therefore consider to be confirmed. The TNS 2022nxe web page still shows the object type as  'Unknown' as of 2022-08-10.
