Great job, Astronut. That was conclusive.

For those who don't trust Astronut, there's the Katkam archives. Here it the pic from Jan 21, at 15:50

The picture before shows the same date and time in 2008. Before that come a number of older comparisons.

The 1st three pics are the nicest though...three sunsets on the same date. Click view all, then go to it.
