Over the weekend, I was back at Kitt Peak, taking more images for our big survey. Things weren't too exciting, because it takes a lot of data processing to know if there is an interesting star in any given patch of sky. For me, it's always a little frustrating to come away from the telescope and not be certain what we may have accomplished.
But, we made progress. We have now taken pictures of 1700 square degrees, which is about 1/25th of the entire sky, or 1/12 of the sky visible at any one time. That's quite a bit! Our ultimate goal is 5000 square degrees, so we are about 1/3 of the way done. That's a good start, but with the rare objects we're looking for, it's not enough.
