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

 

Here's a link to calculate transit times.

Are you sure?

YesI am sure I can see it.

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

Cloudy now- no way to time.. 2318 looks about right

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-
