GRS heads up

[Stu]

Clear here currently. I expect patchy cloud but hopefully enough clear sky to catch a look at it.

10" out ready and raring to go

[Davey-T]

Patchy cloud and windy here not worth setting up as the 10" is like a flag in the wind

May have a look later if the wind drops.

Looks good down here tonight - gusty and cold but the seeing looks pretty good so far :-)

Hi Stu, just watching the moon / shadow on Stellarium and wondering how accurate it is, does it agree with your app ?

Pretty pants here in Bedfordshire lots of cloud a few gaps and little windy.

Strange you say that Dave, no it doesn't match SkySafari unless I turn the light time compensation off which makes no sense.

With light comp on

But with it off this is what I'm seeing

Having said that, I didn't see the moon go into transit. Is Ganymede dark too?

EDIT: to be clear, I am seeing the same as the first image but the moon is dark against the planet, no shadow yet and it is now cloudy. Hoping for a clear patch soon.

Gusty wind here but when it drops and the seeing steadies I'm getting nice views

[Stu]

Ok, I'll blame baby brain for this one!

Skysafari is correct (of course), I just don't remember Ganymede being that dark? So, the first shadow is the moon, and the actual shadow is much darker and sharper, following along behind.

Saw this tonight about 9.20 on juptier in the breaks of the clouds tonight sorry not good at drawing lol

I was set up Saturday night, the skies were clear, but the seeing was absolutely terrible from my back garden - usually when the seeing is bad, you can just get the odd second or two "break" in the seeing - but Saturday night was probably the poorest night I've seen in a while.  I could make out the GRS only by colour with no real definition at all and no breaks in the seeing  - I can usually see detail around the banding with white ovals being really easy to pick out - going off memory I think there was a large storm in the North Equatorial belt more or less directly above the GRS in longitude.

Just have to put these nights down to "experience" - it certainly makes the really good nights remain in memory.

Not so good tonight - had rain showers early on lasting up untill about 9:30 - so another night on the lounge!!

Paul.

Nice one Bugfly, if it helps you remember and observe more detail then it's well worth doing.

I just timed packing away to perfection, it rained about 5 mins later!

[Bugfly]

I was using my 8inch Dobson with wide lenes and dropped down 13mm with a good view happy with what I saw

[SnakeyJ]

Not too bad down here, in between the cloud - seeing was fair to good, but the wind was a real PITA.   Without the constant movement and vibration from the wind, I reckon I'd have got some pretty decent data considering.    Wrong time for the GRS though

Quick RRGB:

Pretty good Jake. Lovely sharp shadow

Conditions got worse here and the wind picked up so I called it a night before GRS appeared.

Well caught Jake, gave up here as the wind got really gusty.
