And I couldn't find any mention of the size of the spots, so I looked up the diameter of Ceres (590 miles) and measured how many pixels across it was in this image, and then measured the pixels of the two spots and did the math to get their size in miles. (They are 20 miles across)

Thank FSM that a smart boy like you, with obviously too much time on his hands, is not a sociopath.

It's so damn quiet here today. There are a few things I could be doing, but I had no motivation. None of it was urgent at all.

All day, I've been researching purchasing a new-to-me camera off Ebay. I need to sell a couple more things to get enough funds built up in PayPal, but I'm toying with either a Panasonic DMC-FZ70 (which is a very nice super zoom upgrade of my current decade old camera) or going up to a DSLR like the Nikon D5100.

This weekend, I'm going to list my old 35mm Nikon gear and hope to get $100 or so. That will put me in striking distance of a DSLR.
