I remember observing the last triple shadow transit on Jupiter from SPOC in March, 2004. We had clear weather, and though it was cold, it was worth the effort to see it. I think that SLAS billed it as a public event, but I don’t remember. I see that there are three events coming up: 12 Oct 2013, 4:31 UT 3 Jun 2014, 19:02 UT 24 Jan 2015, 6:27 UT. The next triple shadow transit after the January 2015 event isn’t until 2032. Unfortunately it appears that only the January 2015 event will be visible from Utah. (Someone else please check your planetarium software to see if I’ve made any errors.) I know some of you may not get that excited about a triple shadow transit, but for anyone who hasn’t seen it, I recommend that you add it to your astronomical bucket list. I certainly thought that it was one of my observing highlights.
