a couple others, amateur radio astronomy and atmospherics effects such as Aurora and Green Flashes etc... so much to do and know, so little time

Robert, with respect (and i dont want to sully this superb thread/poll) I have to say, being both a 'sometimes' pedant and an aurorae observer, that re the classification of aurorae as coming under the 'atmospheric optical phenomena' banner is a sometimes contentious one. Without going into to it fully, it actually is technically under both the astronomy and atmospheric optical phenomena banners, it seems. As you know the aurora is of course caused by the solar winds interaction with earths magnetic field, and happens at the edge of space, and they have been used to study the sun and the solar wind and still are.
"as·tron·o·my (-strn-m)
n. pl. as·tron·o·mies
1. The scientific study of matter in outer space, especially the positions, dimensions, distribution, motion, composition, energy, and evolution of celestial bodies and phenomena."
Secondly I am also guilty of using the term 'atmospherics' to decribe the same things you are - I just used that term incorrectly in here recently - I think it fits the bill too - but it is already being used unfortunately
'at·mos·pher·ics (tm-sfrks, -sfîr-)
n.
1. (used with a sing. verb)
a. Electromagnetic radiation produced by natural phenomena such as lightning.
b. Radio interference produced by electromagnetic radiation. Also called sferics.
2. (used with a pl. verb)
a. Features, events, or statements intended to create a particular mood or attitude: "[This book] is full of fiction unconcerned with spooky atmospherics or suspense; most of the collection's stories are about cruel humans and the violence they commit" Ken Tucker.
b. The mood or attitude so created.'

note in the second site they dont have aurora listed under aop's, and that is a more authoritive site
cheers, and sorry for being a sad pedant and a touchy aurora observer, but i cant help myself it seems
