Thermal Radiation:
Time for maximum radiation: 11.5 seconds after impact
Visible fireball radius: 223 km ( = 138 miles )
The fireball appears 169 times larger than the sun
Thermal Exposure: 7.72 x 10^9 Joules/m^2
Duration of Irradiation: 49.7 minutes
Radiant flux (relative to the sun): 2590
(The physics aren't the same, but just for the sake of comparison: Chicxulub's 4e8 megatons-TNT of energy, at 300 km, is 1/r^2 equivalent to a 4 megaton nuke, at 30 meters).

Altitude 300mi is not the same as linear distance to blast 300mi At 300mi up you could be over a different continent and get a good view and you would probably want to be so that you get a better view from the side.
