Explosion in Atmosphere of Mars Reaction to Comet Flyby?

There are several reports circulating about the supposed ‘explosion’ in the atmosphere around Mars…  A type of reaction is seen in this video.  My question is whether it is indeed an ‘atmospheric’ explosion or something else such as a hit on the comet that then explodes in the atmosphere or some other electromagnetic reaction from a shield being impacted around Mars.   Reports are the “rovers” were not adversely impacted.  No word on how the bases there were affected or regarding any long term atmospheric affects.
