Comments: Personal prediction.
This was in the wee small hours with a fine layer of fog causing me
to use 12 frame integration to see the target with any degree of certainty.
The event was clearly seen 27 seconds after the predicted time.
Whilst the time resolution was poor, it's still nice to get back in the game in 2011!
