I recently posted a request on the Minor Planet Mailing List asking to hear from anyone who happened to be imaging 2012 DA14 at the same time I was. My hope was to find a picture taken at the same time as one of mine and to use the two images to show the effects of parallax. Happily a guy who had been using the Vatican Advanced Technology Telescope in Arizona that night to shoot 2012 DA14 replied and we were able to determine that one of his many images had been taken within half a second of one of mine. The FOV of his image was smaller than mine so I had to do a bit of Photoshopping to align the two and then add a third image taken from the STScI Digitized Sky Survey to show context. I thought that since there is about 800 km between our two sites and 2012 DA14 was still pretty close (~210,000 km) I'd see some parallax but was actually surprised at how much: http://www.slas.us/gallery2/main.php?g2_itemId=68&g2_page=8 Clear skies, patrick
