BS: Moon and Jupiter - astronomy question

I have noticed that it looks as if the moon will pull across and obscure Jupiter for a couple of hours this evening. Is there any special astronomical term for this occurrence? I just wondered idly when this last happened on Christmas Day!

Bugger - a man of my age ought to be able to spell astronomy!

If the moon oasses in front it is called an occultation.
I do not think it will happen though.
Just being close is called a conjunction.
It is very close tonight.
Worth a look.

Thanks Keith. I will keep an eye on it. It looks like it is going to be a near thing!

It seems not. There was one this year, tho -- on 15 July.

I don't know whether "transit" applies in this case or not. If Venus crosses in front of the sun, that's referred to as a "transit of Venus." Venus appears on the face of the sun as a small, black disc, but you can still see the sun (with proper equipment so you don't fry your retinas).

But the Moon would completely obscure Jupiter, so occultation would apply, but "transit?" Hmm. I dunno. Maybe not.

Hubby the astronomy prof says it's a conjunction.

Something would have to be scarily close to transit the moon.

It was a glorious sight from north Cornwall, with the moon and Jupiter appearing to race together though fast-scudding clouds. I got everybody out to have a look. No mean feat on a boozy Christmas night in!

"Something would have to be scarily close to transit the moon."

Will likely happen in 2029.

Moon in front of Jupiter- occultation

Jupiter in front of Moon -BIG problem! But we would not be here to worry about what to call it, afterwards.

May I suggest HFB?

I checked out - there was an occultation visible from parts of the Southern Hemisphere. Very close conjunction hereabouts.
