I believe this to be Nature Filtered Sun ?.An event that occured in the skies over the San Francisco Bay area. What caused this to happen ???
I observed this event,captured it on a late afternoon {hazy} sky.The Sun had a "halo" effect for aprox 30 min. I believe this is a rare sight, I don't know anything about ths.
I slapped on a STACK of filters to wipe out some of the radiation. hehe.
Do I have to list them all ? Count them 6 maybe 7.you tell me! : Interesting effect,I'm not blind from staring at the sun. :O)

Call it an X-file
