Flare on OGLE-TR-10 during transit

We report a stellar flare occurring during a transit of the exoplanet OGLE-TR-10b, an event not previously reported in the literature. This reduces the observed transit depth, particularly in the u'-band, but flaring could also be significant in other bands and could lead to incorrect planetary parameters. We suggest that OGLE-TR-10a is an active planet-hosting star and has an unusually high X-ray luminosity.

Have to wonder what that system looks like from close up... could be pretty spectacular (and very, very lethal).

Got a little bored / creative.

Well, if the surface of the star that has been "stellar flared" was near the planet, the weather on the planet must have been very cataclismic. At this distance, the flare has probably caused a temperature increasing, plus some interactions with the magnetic field (if the planet has one) like auroras (quite common), magnetic discharges in the black sky (calculating the albedo - 0.103 -, the planet tends to be black like HD 149026 b, giving a temperature of 1.563 K, but it would be higher due to the tidal lock), EM spikes if the EM field is weak, and maybe strong hot winds moving from the day side to the night side. But, it's only some expectations...
