I found it on 2014 April 21 20:00 UT.
Now, you might say that its not perfect. But, for goodness sake that's really close! I'm pretty proud of that one. Consider:
1. The GRS is a cloud formation that drifts about with respect to the cloud formations in the band around it.
2. The cloud formations in the band drift over time as well and they are difficult to pin down over long periods of time.
3. We can only track either of the above based on amateur observations that are difficult to make without a clear point of reference
4. Every other commercial software that I know of simply uses the current location of the GRS (e.g. today) and it would likely put the GRS on the other side of the planet
When I set up SkyTools to predict the position of the historical position GRS, I didn't have such a well-defined example to go on. I mean, exactly when does the GRS cross the center meridian? Everyone is just eyeballing it. With this observation I should be able to nail it down much closer.
