Eclipse of Europa by Io
In a previous post in Astronomy News, I alluded to the upcoming deep partial eclipse of Europa by the shadow of Io.
This took place a few hours ago between 2:34 am and 2:38 am local time. Having had rain in the past 24 hrs, I was expecting a heavy fog to form and it did not disappoint. This was accompanied by equally heavy dew. In anticipation of this, I decided not to leave a scope out for the night and setup to photograph the event. Instead, I pursued a simple visual observation. I put my ED80 refractor onto my Manfrotto 475 tripod. The 475 is very solid and designed to easily and rigidly hold payloads up to 12kg and the whole thing can be set up in a few minutes.
I set up the tripod and scope at 2:28am, just a few minutes prior to the start of the event. The predicted magnitude drop of 1.4 magnitudes is not much. 5.5 magnitude Europa will drop to around magnitude 7.
I spent the few minutes before the event calibrating my eye to the relative brightness of the various satellites. As contact occurred, the brightness faded, very slowly. Had I not made the brightness comparisons prior to contact, I may not have been sure whether I had seen it or not. With those visual brightness comparison references, it was obvious. The fade was very slow and gradual taking half the duration(~2 mins) to fade and the other half of the duration to re-brighten again. I have observed many Jupiter phenomena over the past four decades but I believe this was the first satellite to satellite eclipse I have observed. There are a few more events during this "Season of mutual phenomena" I may have a go at photography or video of future events over the next few months.

Re: Eclipse of Europa by Io
VERY cool!!! How the heck did you get pictures of that size?
I couldn't resist checking my Manfrotto. It's 055 and should handle 9 kg.

I didn't take pictures, just visual.
Are you referring to the animation on the Astronomy News item?
That's an animation generated from Starry Night software.

Re: Eclipse of Europa by Io
That must have been quite a thing to see!
Are you going for any more during the Jovian equinox?
You should be able to see Io eclipsing Calisto on the 12th from your part of the world.

Re: Eclipse of Europa by Io
Hi Michael and gang,
Thanks again for theVROD . Even with my 40 + years as an observer, this was a first for me too. I have missed the other "mutual event seasons" either because I was unaware they were occurring or just busy with work and not doing much observing at the time.
I have a friend who took up astronomy a year ago and I have been mentoring his journey into astronomy. He has quite acute vision, in fact better than mine. When we both look through a scope, he can see things that my astigmatic eyes just don't see.
I spoke to him yesterday, He observed this event and did not pick up the change. He said he wasn't sure if he was seeing the event, fading, or not. If you want to try observing one of these, the step I took of calibrating your vision by comparing the brightness of the eclipsed satellite to other satellites before the event is key to detecting the change.
Then during the observation, you need to keep repeating the comparison. The change is so gradual and small that you don't see the change on the planet alone.
Thanks again.
Joe
