Hello all.

I was visually observing the moon last night from my home in Central California through my 10-inch Dob, when I saw a refractive "wave" move across the moon, from its southeast to its northwest, clear as a bell. Time was approximately 8:18pm PST Tuesday, November 24 (04:18 Wednesday, 25 November UTC).

I know others have seen and documented this phenomenon, as I have seen several of their videos posted on YouTube over the past couple of years, but I had never personally witnessed it through my own rig until last night.

Has anyone else seen this? And is there any consensus as to what it might be/what is causing it? I've always suspected it might simply be a local disruption in our upper atmosphere, but I've never seen or heard anyone else's theories/conclusions.

Thanks in advance . . .

Thanks, Frank.

There was, indeed, a single jet that passed overhead at cruise altitude, about a minute before my observation.

I should've put 2+2 together.

You rock.

Yeah, frank's got it right, up there. That would at least account for 99+% of such sightings. I once (and only once - 1980) saw something like that associated with a VERY bright meteor. The fat "contrail" of the meteor persisted and interestingly twisted, contorted and drifted sideways. I was looking thru a 17-inch Dobsonian at about 150x.    Tom

Jet or Jetpack?
I finally located this 3 second real time (slowed 3x) clip made while videoing with my cellphone.
