Note the funds are from the second year of my grant (Sep. 15th start) which were deposited into my university's bank account in August...

Perhaps it is just the Chilean public education system or my university, but I have just had to cancel my third conference and invited talk as my university administration has failed to book my flights and hotels in time (I requested the use of funds four months ago) on time...

I want to apply a flare model along the axis of travel and see what we get. Could be interesting to ask the SpaceX folks if they know what a feature could cause a glint that lasts less than 50ms.

Please feel free to do so 🙂.

I would guess limb darkening or apparent changes in the stellar radius due to changes in the host star variability. Sadly I don't have access to any telescopes that can point that north at the moment.

A year later I started my 2 year NPP fellowship there (2014 to 2016). I still miss the Redwood forests and In-N-Out burgers but not the property rental prices...

If you like, to test the spot theory, I could run the transit through PRISM and obtain an estimated temperature for the spot. We can then test if we get a realistic temperature for an M2 dwarf star?

True that binning would help but you would lose temporal resolution. That being said, have you calculated the energy if the anomaly was produced by a flair? It would be interesting to see the change in amplitude across the spectrum.

It does not look like a typical spot crossing as it is missing the initial flux increase typical of the planet entering the ingress of the spot. It might be a flare as you say, but the amplitude looks only a sigma or two above the RMS scatter in the data, so it might just be noise...
