In watching the SpaceX SES-12 launch last night, I noticed what looked like the fairing of the rocket glowing a bit a while after launch. This was most obvious in the SpaceX video SES-12 Mission about
T+01:30 to T+01:50. My first thought was this likely was just a reflection off the bottom of the fairing of the bright rocket exhaust during the night launch, but it seemed more steady and all the way around the fairing's circumference than what I would have anticipated just from reflected exhaust glow.
So, my question is whether this perceived glow was actually aerodynamic heating of the fairing (and not reflected light), and if so, what typical maximum temperature does the fairing achieve during launch?
