In my zone the GRS will transit 11:18 PM.

 

Here's a link to calculate transit times.

If you can time the transit it would be helpful towards deciding which reference was the more accurate?  I’ve been clouded out tonight.

Interesting. Your report suggests the S&T web-based calculator gave the best result tonight. 

 

My Sky Safari 6 app predicted 30 minutes earlier, 22:48 EDT.

The gist of my post was to alert the group that the GRS would be located on or about the meridian for good observing based on S&T website.

 

I don't use computer programs- more or less I am old school.

I use http://www.shallowsky.com/jupiter/ which is very similar.  The GRS should be visible from 10pm to about 12:45am EDT tonight.

 

I used the website last Friday June 21 and it was right on.  Not only did I see the GRS, there was a transit of the moon Europa concurrently.  Kinda of weird but I needed averted vision just to see the tiny shadow--smaller than a pinpoint at 250x.  Doing other things tonight, so not observing.  Enjoy-
