I'm new here, so if I've done anything wrong, please let me know.

I've been taking a look at some photometry data collected from TESS, and I encountered this light curve:

light curve

(please ignore the blue and orange lines, I was trying to run some statistical analysis on the data)

I haven't seen a light curve this curvy before, and I was wondering what this was indicative of.

I was also wondering about the spike at around time 1326, would this potentially be an outlier?

Thank you!

    $\begingroup$ Can you show the curve in a smaller range arounf 1326? My first impression is that this is a spotted star, with a rotation period of around 5 days and that the feature you have identified is a flare. A typical flare will show an abrupt rise and a slower decay. $\endgroup$ – Rob Jeffries Jan 22 at 23:21
  • $\begingroup$ "This curvy"-- do you mean the cycle frequency is high, or the peak-peak ratio is large? $\endgroup$ – Carl Witthoft Jan 23 at 18:44
  • $\begingroup$ @RobJeffries, sure, here is the bigger image around 1326: imgur.com/a/MNLhqFj Thank you so much! $\endgroup$ – nywillb Jan 23 at 22:58
