Shadow of Io to eclipse Europa

[OzEclipse]

Hi All,

There is an occultation or eclipse of Europa by the shadow of Io on May 9th from 16:34-16:38UT

These events are a little bit rarer than the other Jovian satellite phenomena occurring only when Jupiter is on its ascending or descending nodes once every 5.5 - 6 years.

I have prepared a short article about it on my website. I prepared this for my networks down here so it is in the UT+10 time zone, in Universal time- May 9th from 16:34-16:38UT

Bummer, it is 9:34 in the morning here in CA.

I realised that it's going to be in daylight or below horizon for many. But I figure we have members scattered all over the globe and a few here in Australia. @DeanD @Ozypic @ab1963

Thanks for the heads up Joe. I'll be at Blinman in the Flinders Ranges that morning: packed up and ready to come home...
Might be a late night instead (although 30 minutes earlier that you!).

Good luck,

Dean

It may not be impossible: I have seen Jupiter's moons in the daytime (not easily though!!!), and Jupiter will be reasonably high for you if I read Stellarium right. It might be worth a try with your 9.25 Celestron, and in any case even if you can't make out the moons (maybe because they are eclipsed! , you will still have bragging rights that you saw Jupiter in the daytime...

Good luck!!!

Hi Dean,

Looking at the shadow passage, I suspect the brightness will drop enough for this to be easily detectable. I can see all the Galilean satellites in a good pair of binos. If you have a good pair of binos or a good finderscope or small refractor or cat, I suspect you'll be able to see it.

Weather permitting, I'll try to photograph it with a VIxen VC200L and observe it with a dob. But I will try spotting it in binos before the fade and during the eclipse to confirm if I would have seen the fade.

I think it started to rain the day you posted this message Joe !.
In fact it rained that hard ,the water running through my backyard got high enough to run across my garage floor. An unusually rare event...
Anyway its been pretty much cloud cloud cloud ... and there wasnt a star to be seen last night... I hope someone else had some luck with the Jupiters moons... Lo's shadow eclipsing Europa...
Jeepers... Im not sure I could have noticed it anyway... Phill

The event is tomorrow morning...May 9th, 16:34 UT is tomorrow morning at 2:34 am on May 10th in EST.

It's perfectly clear out here tonight.

Oh Crickey ! Just one little day Joe , 24 little hours ! and of course its clear out there in paradise ! It looks great out there... hahaah
At Dinner time here it was fully clouded in and actually spitting rain, then 11.30 when I was going to bed there wasn't a cloud in the sky......
I got my binoculars out and had a peek at Jupiter as it was just creeping over the roof of my house. and as usual I was wobbling all over the place. The colour seemed to wash across jupiter like it was under water, but the stars weren't twinkling.... So I put my camera on a tripod and fiddled with that , but I knew I was wasting time, I've never got a good pic with it... I knew I was going to have to get my refractor out.....
Why haven't I bought a decent one yet .... and the mount ...its not worth a damn.... it wobbles more than I do.
The wife turns the back light on grrrr and says WHAT ARE YOU DOING ?
Oh I'll be in soon dear. its just past one , an hour or so to go. I had the scope out a few weeks ago for a quick look so its all assembled but no!! its one in the morning, I cant put that roll a door up, it wakes the dead. yes I've had the roller door talk with the neighbors, its right next to their babies window, sigh , why do people have babies.
ah so I take it apart to fit out the two doors, move the alien, hes got no eyes yet, so he doesn't know why hes getting moved in the middle of the night.

I plonk down the tripod in the wet grass next to a maple tree, trying to hide from the 4 street lights I can actually see in my backyard. and NO I'm not leveling it. Put the scope on the mount. NO I'm not balancing it.
I run the power lead out, co ordinates yes, time yes, time zone +10 yes, daylight savings no , ready to align yes ..... hmmm mostly behind trees . lets try brightest star in eastern sky... yes Jupiter yes... and then a star with a name a mile long I cant remember. You would think that's enough but then it offers up another star , select yes and away it goes to the tree next to me. Align the scope to the invisible star yes.... I just click yes, select Jupiter and it lands in the view finder.... well that's a first ..
I look at Jupiter through a 10mm plossl and a 2x Barlow giving me 120 x but the view is bad, no detail just blurry. But
I still put the zwo 120 camera in with a 3x barlow and a 2x barlow , manage to find Jupiter again , and focus in using the bartinov mask. of course I lost Jupiter then . I finished up taking the 2 x out and just have the 3 x and find it again just in time to be to late to see an eclipse .. sigh . oh well I'd assume that the moon would just disappear for a few seconds. and I managed to make it all disappear for ages anyway.
I think I need to just put the camera aside and concentrate on looking. In hindsight what was a pic of a little speck going to show me ?
Oh well better luck next time, I wonder how other people went ? Phill

Phill,
That's why I decided just to watch & enjoy this one!

I posted an observation report here
