    Hey @erorick72 -- welcome to the Zoo!

    I personally am not very good at transit-spotting, so I will defer your questions to one of the experienced volunteers... but I just wanted to assure you, someone will be along soon to help you out! 😃

    Dear erorick72

    I'd say it's a processing artefact, a not perfectly corrected thurster fire event. If you zoom in to the maximum you see that the dip is just before a missing pixel. This sometimes leads to an imperfect correction.

    Have a look at https://www.cfa.harvard.edu/~avanderb/k2c1/ep201534061.html

    You see how many events were in the raw light curve and how the correction worked in many cases (but not always in all of them in a perfect way). It's really a difficult task to clean the raw light curves in my opinion.

    But if you still feel the event is a valid drop, just go ahead and mark it.
