Revised photometry and new photometry

Upon further analysis, my prior photometry was too faint.  A value of 19.5 +/- 0.3 was now obtained

For 2023-02-04 (JD = 2459979.68760) the transient measured 18.8 +/- 0.1 with V as reference on stack of 8 exposures of 120 seconds each Luminance with T18.

Possibly a fast transient

Image taken with T18 of iTelescope.net showed an object at magnitude 20.2 +/- 0.7 with V as reference on stack of four 120-second exposures during a waxing gibbous moon. If I have identified the correct target, it has faded substantially since discovery.
