TESS catched a bit of strange (on my POV) flare of fast-rotating active giant FK Comae, which coincides with maximum but not with “spotted” minimum, as previous mini-flare.
BTW FK Com may show stronger flares: 1999A&A…343…213O
Nice flare.
The problem with TESS though is that TESS data may show similar features and they end up being artifacts. You can see that when you check data on well-behaved (not active) stars.
This one looks real though, the light curve is consistent and we know that it is FK Com and it does these things!
They are difficult to catch though because once you see them, you can’t predict when the next one is going to happen.
