Hi John,
Just got back from another Lawn Bowls trip, this time for my son.
When I saw the title of your post my first thoughts were that you must have finally run out of car polish
.
Thinking about it though, any data is better than no data.
An as yet undiscovered asteroid could have collided with Jup as you were capturing data and the flash would still have shown up even at this quality so it is still a worthwhile exercise even when the conditions look crook.
Regards
Trevor
