Heads Up, Jupiter Looks Busy on Saturday Night..

[Fozzie]

Just noticed this in respect to satellite events on Jupiter.. My neck of the woods is showing a clear forecast (currently)..

Looks like there will be some good regular action on view for Jupiter, for most of the night. Copied this from the link below..

I = Io = innermost satellite
II = Europa
III = Ganymede

III: Tra start: 3 Jun 2017 21:49
II : Occ start: 3 Jun 2017 23:58
III: Tra end : 4 Jun 2017 0:16
I : Tra start: 4 Jun 2017 1:05
I : Sha start: 4 Jun 2017 2:10
III: Sha start: 4 Jun 2017 2:20
I : Tra end : 4 Jun 2017 3:16
I : Sha end : 4 Jun 2017 4:21
II : Ecl end : 4 Jun 2017 4:34
III: Sha end : 4 Jun 2017 4:37

Im Assuming here that Tra = Transit, Occ = Occulting, Sha = Shadow, any one fill me in on what Ecl means??

Happy viewing, if we get the chance..

Interesting activity, indeed. I assume Ecl stands for Eclipse (when a moon is not occluded by Jupiter, but is in its shadow).

[Peter Drew]

As Michael correctly says Ecl stands for eclipse. This is one of the more interesting of the Jupiter moon phenomena. As the moon comes out of eclipse you first notice a minute faint starlike point of light which gradually blossoms up to full illumination. Quite dramatic.  

[Fozzie]

Eclipse.. of course that makes perfect sense..  Think I might have seen one of those the other night, without realising.. I thought it was just the encroaching darkness that made the moon "pop" into view, but it might actually have been an eclipse.. must look out for it again..

[Stu]

Good stuff. Only problem is that Jupiter sets at 2.48am so will be very low for any events that are visible.

I note that it is very close to the moon as it sets so that will be worth a look or an image. Looks to be under 1.5 degrees apart whilst still 8 degrees up which might be doable with a good horizon.

[johnfosteruk]

I'd love to have a go at observing and imaging that lot but it isn't going to happen. Establishing goodwill with a night in tonight.

[Stu]

I have a night to myself tonight, other than getting a three year old to sleep!

Hope to have a bit of a go with the C925 tonight.

I've just seen this moon/jupiter close pass at dusk.. I'm setting up the 72mm/750eos combo.. should be able to get a good portion of both in frame... albeit with no scale on jupiter but still... nothing to loose their I feel..

Snap... I've a 2half year old to get to sleep... although as I've accidentally kept him awake from half6 this morning I rather fancy my chances of being on my tod by half7!

Weather set well here  -  thanks for the details.

Sadly so far hopeless here tonight.

The clagg has rolled in with solid grey and continuous sticky drizzle.

The good news is that it is heading North, so anyone unable to observe due to family commitments  around the Plymouth area won't miss anything.

[Stu]

Likewise here Richard. Forecast was quite good, but it looks pretty murky and feels a bit stormy out there. Don't rate my chances.

Supposed to be clear early so perhaps a little solar....

[Fozzie]

Just waiting on the last of the whispy stuff to go.. the 72mm ed and 750eos give me almost 3x2 degree so should be more than enough for the close moon/jupiter shot..

Plan then is to load the starwave up (or maybe the 200p) and get some Luna close ups done..

[Stu]

Good luck! Not much wispy about the stuff over here  

[Fozzie]

Errrrrr yuk that's bad luck Stu.. 

[andrew63]

You can borrow some of mine Stu !

Going to set up outside in a minute to look at Jude. Can still see blue sky out there so fingers crossed! ??

Excellent, contrary to my previous comment, I've been granted special dispensation to go out but I do have to be up early in the morning for car boot sale and farmers market.

So.... SkySafari tells me that my 70mm frac and the Nikon will fit the both of them in from 00:15. Clear Outside says the weather will be good so I'll be there. Plus, I've just been out observing and imaging the afternoon Moon and the seeing is good too. Will this be one of those evenings when it all comes together? Skeptical? Me? Mmmm.... You never know I might even find some gems at the car boot.

I captured the close pass a little while ago but that was with the 102 and it didn't have all the moon in it so I'm quite looking forward to tonight

Clear Skies all.

 

[Fozzie]

Nice John... I've just been out trying to frame and no joy... just after midnight you reckon? ***dumb question alert*** are they getting closer now? I thought I'd missed it?

[johnfosteruk]

Good timing, just off out to catch the Ganymede transit. Had ten mins with GRS looking lovely just now too. SkySafari says they close on each other until about 01:30 then parting as I recall but 12:15 is when they're close enough for my FOV. Besides they'll be too low for me by 01:30

Enjoy

From what I can see, they are 2 deg 44' apart now, and will continue to close up until after Jupiter sets.

They will be just over 1.5 degrees apart at 1.30am with Jupiter at 10 degrees altitude. Should look great!

[johnfosteruk]

And I've just remembered project Pluto times are UT aren't they silly me. 

I'll catch GRS moving off the disk then see the Ganymede transit in an hour. ?

I was watching Ganymede thinking their times must have been off for a moment or two until I remembered!

You're taking the proverbial Rich. as discussed since my previous comment I'm outside now so you can keep your poxy clouds 

[Fozzie]

I've got a cloud of midgys.... feeling a bit itchy already.. could be a long night!
