Io will occult Europa, Nov 23rd 0716 UT

[stevend]

I have just got this from my weekly Night Sky Guide digest: http://news.nationalgeographic.com/news/2014/11/141117-starstruck-sky-events-this-week-sky-watching-astronomy-science/

"Jovian Moon Eclipse

Early risers on Sunday, November 23, will have a chance to witness a special type of eclipse involving two moons of Jupiter, starting at 2:16 a.m. EST. Visible through even the smallest of backyard telescopes, the moon Io will occult (cover) fellow Jovian moon Europa for a few minutes just off of Jupiter's eastern limb.

Look for Jupiter in the early morning hours high in the southeast, next to constellation Leo's bright star Regulus.

Because Jupiter is so overwhelmingly bright, it will be best to move the planet just out of the field of view when looking at this Jupiter moon eclipse through a telescope."

This is just before dawn so might be viewable in the UK if conditions permit.

Should be a great sight. It might be a bit light here at that time in the morning. Looking forward to the animations from our friends in the north.

The GRS, Ganymede shadow transit and the Europa / Io eclipse!!! Can it get much better?

Wow (and thank you) , for some reason I did not check my GRS and transit tables.

Sky Safari shows a partial occultation right on the limb of Jupiter at 06:36 GMT.

The sky should still be dark enough to see this if it's clear.

[Paul73]

My Sky Safari shows it at 07:18(ish). Looks a lot closer to the limb than the S&T version. Wonder which is correct?

That's excatly how my Sky Safari shows it, just the time difference.

EST given as 5 hrs behind UTC which by my reckoning would have put this at 07:18 local for the UK.

Someone somewhere hasn't corrected for DST (most likely me!)

[Paul M]

Panic over, I hadn't got the option set for light travel time.

It is indeed 07:18.

Be too light by then?

[Paul73]

Yes. Too light.

Did anyone capture this?  Any photos or videos available?   I am very much looking forward to the triple transit on 24th January 2015, last one until 2032.  Fingers crossed for a clear sky!

A saturday morning; 6.28UT Io, Europa & Callisto. I will put it in the calendar.

I get quite excited about a double transit so, I too have now got it in the diary.

Should be a nice one to watch develop. The bright Io will eclipse Calisto's shadow for a couple of minutes about 5 mins before the third shadow hits Jupiter's disc.

It is now in the SGL calendar. http://stargazerslounge.com/calendar/event/1000-triple-shadow-transit-of-jupiter/

I just looked at the January 2015 triple shadow transit with SkySafari.

The third shadow arrives on the disc at approx 06:24 GMT. 

But, according to SkySafari, Io actually occults the shadow of Europa (I think it's Europa's shadow) starting 06:18 GMT.

That'd be interesting if it happens!

Edit: No, it's Callisto's shadow (I think!)

This had better be a triple alarm clock jobby. I can't see a UK viewable triple shadow transit in 2032.

And checking out your view of the western horizon. It is right on the limit for me so I may need to consider a remote site (and hoping remote means near by).

I hadn't thought about that. Anyway Jupiter should be about 21 deg above the W horizon from home.

A bit near the bone. It's possible I'll be in Cumbria at the time so will be ok.

Just down to the weather now.
