List of Jupiter Moon Transits 2012-2013

Recommended Posts

Hi all,

I was out on the 28th October (Sunday) waiting for the Great Red Spot to appear on Jupiter. As I was watching the GRS move across the disc I noticed what I thought initially was a speck of dust or defect in my eyepiece. My initial panic subsided when it moved and I realised I was watching a moon shadow transit! :)

So I was treated to 2 events that night but it's been annoying me that I didn't know what moon it was. I'm having trouble setting up Stellarium to give me reliable data (I have location, altitude and time set up correctly) for Jovian event predictions.

I much prefer a bit of paper anyway and I found this on Sky and Telescope web site; it gives the start, midpoint and end of all Jupiter moon events. Hopefully someone will find it useful if you haven't found it before


According to this it was Europa masquerading as dust! :D

They really are beautiful sights and Sunday was very nice.

Sunday was amazing! The seeing wasn't too bad either meaning I was getting moments of quite a lot of detail in the belts. I was concentrating on that when the Europa transit surprised me.

If you haven't seen it yet, you may also like Sky and Telescope's Java Script which plots the moons within minutes of each day.

Or use "WinJupos" or "Jupiter 2" both of which are freeware.

'Jovian widget' is a nice little Android app.


Thanks for all the software tips, saves a lot of time. Faster than getting stellarium sorted. I've printed out an A5 booklet of the pdf to go with my planisphere for the times when I don't feel like turning computer on (I get allergic to them after work :) ).

      Hi Guys!
      My name is Daniel and I am from Ecuador, I love astronomy and the secrets our universe holds. I love Jupiter, our big brother, so I opened this forum to talk about facts, secrets, theories, etc. About our gas giant!

      Hello All,
      This is a photo accurate representation of how I've seen the conjunction through a Skywatch 14" f4.6 Dobsonian, using the 17mm Ethos eyepiece combined with the 2X Powermate during the observation of the great conjunction of Jupiter and Saturn, and how well both of the planets fit into the eyepiece field of view.
      My location on the east coast of Australia was totally overcast for the last week and this evening I had a small window of opportunity to actually have a glimpse of the rare event, which no doubt, I will not have a another chance of experiencing in my life time.
      This happened about 17 hours after the actual closest point between the planets, and most likely the difference would be so small that it wouldn't be noticeable without direct comparison. 
      This image was composited by first taking a series of shots through the eyepiece using an iPhone, I chose the best frame of the series than superimposed the overexposed planets with images of the planets captured separately with enough transparency as to accurately show how the planet details looked in the eyepiece.
      Observation time was 22 December 2020 @ 09:51 UTC.
      Clear Skies,

      So I originally planned to go to a good vantage point from the top of Pendle hill, watch out for witches whilst there. It is a local and well known Lancastrian landmark. However my wife is recovering from hospital treatment and so I didn't want to leave her so made do much closer to home.
      A short drive (2 minutes) took me to a place aside the motorway slip road but with a clear-ish view of the setting planets. I was only use 10x30 bins so the view was not particularly well defined but still impressive when considering distances and such. 
      Anyway it is in the bag but would like to do better if at all possible. 
      If the skies are more obliging tomorrow I may venture out with the EEVA set up and grab some data, however the forecast is not so good.
