Io plus shadow, and GRS, this evening

[chiltonstar]

If the weather forecasts are correct, the sky will be clear in many parts this evening.

From 21:30, Io plus its shadow (very close to each other) and the GRS will transit together. The best time will be about 22:30, when Jupiter will be about 12 degrees above the horizon.

Nice heads up. 

Might catch the tail end weather permitting.

I love the moon transits near to opposition where the moon and shadow are so close you can often spot the moon, where there is enough contrast.

Totally agree. It’s a lovely reminder of the mechanics of the solar system and the relationship between sun, Galilean moon and Jupiter. Have seen, at least once, the shadow as a crescent with the moon partly covering it, very nice.

Thanks Chris, I'll be so on this if it's clear hear later

Will give this a go tonight. For those interested in such events there is another in a week (9th May) when Io is actually due to cover its own shadow (as mentioned by Stu) because it also Jupiter opposition on that day

Interesting.  I've seen the shadow once a day or so after opposition as a vertical bar on the "wrong" side of Jupiter. Let us hope for some nice clear nights now we are into May! .

Well, I’m setup but I’m doubtful that Jupiter will clear the house in time

No chance for me tonight but next week for opposition is looking good!

Me too, my neighbours house with the curtains open and lights all on is well and truly in the way  I've come in for now and I'll try again in an hour!

Have fun to those that can see it

The seeing wasn’t great but managed to get this. The GRS  was much easier to spot than the shadow. The shadow appeared 2 or 3 times when the seeing steadied. Nowhere near as clear as the shadow I saw a couple of months ago. Still enjoyed it though. Many thanks for the heads up

Yes, GRS clear, but the shadow more difficult. Looked better in my ED80 than my small Mak because of the poor seeing.

I had a go at imaging Jupiter last night for the first time with my guide camera. Didn't look great tbh but I've only recorded a couple of minutes worth. Haven't tried to stack any frames but will give it a go later. Was around midnight so would have missed this anyway.

Me too, it was wobbling all over the place and I was too late anyway by the time it rose above my neighbours shed. I very much doubt I'll have anything to show.
