Weather / Aurora Borealis from front porch 10 OCT 2024 2324 UTC
« on: October 11, 2024, 0128 UTC »
Aurora after a G4 at 2258 UTC. This is looking north from front porch with surrounding hills in black. Others in neighborhood caught some greens. I am 15 miles due north of Long Island Sound.
From Aurora Zone:
"We don’t see red in the Aurora Borealis too frequently and the colour tends to be associated with intense solar activity.
Reds appear in the Aurora when solar particles react with Oxygen at higher altitudes, generally above 150 miles. At this height the Oxygen is less concentrated and is “excited” at a higher frequency or wavelength than the denser Oxygen lower down making reds visible."
