You guys are lucky. Here in California, the only
atmospheric oddity
we ever see are from the residues of the occasional rocket launches
from local AFBs.
Man I must be a skywatcher because I was only in CA for 4 years and
I saw two Vandenberg rocket launches in that time. No advance warning,
just look up and it was there. They launched them right after dusk across
the sun terminator seemingly for extra effect.... Looked great!
