Re: Solar Eclipse 2024
General consensus is that it's time you threw away those old flannel PJs.
Especially if you plan to travel out-of-state!

Excuse me Chris. Those are LOUNGE PANTS.ChrisGreaves wrote: ↑11 May 2023, 09:10General consensus is that it's time you threw away those old flannel PJs.

And, as I'm from Florida, everywhere else above 25 degrees latitude is too cold so the LOUNGE PANTS stay!

Which is, perhaps, what leads us to the "shift and stack" mechanism.ChrisGreaves wrote: ↑09 May 2023, 22:56Which is what we should expect from solid bodies that are aggregates of a single mass of dust in motion around a star.

Re: Solar Eclipse 2024
Good one Chris. I've not seen this. I wonder what the average frequency of solar eclipse events is on Saturn with 145 moons?

Re: Solar Eclipse 2024
Solar eclipses on Jupiter (very frequent)
Solar eclipses on Saturn (frequent)
Solar eclipses on Uranus (rare)
Solar eclipses on Neptune (rare)

Re: Solar Eclipse 2024
Since 1959 it has been making sense to me: Mister Venus Entered My Jolly Submarine Under the North Pole!
I will suggest that if Mine Host Mines a little deeper he will find that Solar eclipses on Pluto are even rarer still, while those on Mars and Earth ...
Cheers, Chris.
P.S. I suppose that in part this will be due to the nearness to the sun impacting the ratio of the apparent sizes of the moons compared to the sun.

Re: Solar Eclipse 2024
Yes, I didn't think that through! I just got excited about Saturn now having 154 moons! But Jupiter has a very small rotational tilt with respect to the ecliptic, so it's moons trace shadows across it's surface all the time. I've seen a few through my telescope.

Re: Solar Eclipse 2024
Graeme, thanks for blowing my latest mis-guided theory out of the water.
It is by such tests and corrections that science progresses, and by which I limp towards being a scientist.
Theory, test, back to the drawing-board ...
Cheers, Chris

You're welcome!
Here's Stellarium's view of Io's and Europa's shadows on Jupiter this Wednesday early PM BST:

Re: Solar Eclipse 2024
Amazing final image. I'd hoped the caption included more information on the camera and settings of the exposures. I'll need to practice if I get more than one good photo out my attempt.

Re: Solar Eclipse 2024
Hi Graeme. Things is changed. I just have to stand in my driveway and shake my fist at the cloud cover.
And I know what the rest of you are thinking: "Now we know the reason why Chris Moved from Toronto to Bonavista!"
Wrong!
I moved because I can make compost here; once the snow melts. These are some of my one-cubic-metre bins.
Cheers, Chris

Right under the centre line! :Envy:
Even with clouds you will still experience a two minute night in the daytime! I look forward to reading your report.

Hans, I have given this a little thought. But only a little.HansV wrote: ↑15 May 2023, 16:31Solar eclipses on Jupiter (very frequent)

A great deal depends on one's definition of "frequent".
Jupiter | 61,418,738,571 | km2 | 120.41 |
Saturn | 42,612,133,285 | 83.54 | |
Uranus | 8,083,079,690 | 15.85 | |
Neptune | 7,618,272,763 | 14.94 | |
Earth | 510,064,472 | 1.00 |
For an individual in a fixed place on Earth, compared to an individual in a fixed place on Jupiter, the Earth-bound individual must have 61 times the opportunity to witness an eclipse, based on the surface area to each of the 8,029,044,000,000 individuals and counting, no?

Re: Solar Eclipse 2024
Graeme, I have been thinking about this.
I am nowhere near your ability to make(1) photographs of astronomical events.
I am not even in the same lake as Ken when it comes to whipping out a smart phone.
My calendar note for April 8th now reads "Remember not to put thumb over lens"
That said I thought that, regardless of cloud cover or any other aspect of the weather, I might take a set of FIFTEEN images, three each afternoon of April 6th, 7th, 8th, 9th and 10th, each image at 1715, 1730, and 1745. The images should be aimed at the same spot, say the skyline where the sun normally sets at that time of year.
What think you (and what think you-all)?
There are a gazillion images of the sun during a solar eclipse.
But an array of images showing a measurable degree of light might be interesting?
To the best of my knowledge my LGK30/Android phone does not have a light-meter.
(1) Why do some folks make photographs while other folks take photographs.
Cheers, Chris
