Thanks a lot for sharing! Great data!
For completeness: the SN on Astro-COLIBRI: SN 2024chx

Did you take that lightcurve? What telescope did you use? And what are the dates of the lightcurve? (the labels on the x-axis seem strange)

Hi
yes it’s my LC I took the data from February the 13 to March the 15, the X axis is BJD-TDB each point is a stack of 8 to 12 exposures lasting 300 sec.
my setup is a Planewave cdk17 inches, localize in Chile. Usually I do LC for exoplanets, but I want to work on something different for sometimes.
