Our apologies to all who helped and empathy to Bob Ross for what sure looked like a good candidate. Giuseppe and I had a chance to image the field the following night and saw that our "SN suspect" (= asteroid 1887) was no longer there. We were puzzled, though, on our original image where asteroid 5240 was. There was a very close double star in our image that was not obvious on Vickers' image. Usually his images are pretty crisp. Our second image resolved that problem and showed that after blinking the two images, the motion of 5240 was obvious, but it did take a day. An hour or two was not sufficient to detect motion; another wrinkle in this SN hunting business: an asteroid that doesn't move! Unfortunately most amateurs are only able to be out observing one night at a time, thus making day to day comparisons difficult at best. Thanks to the ISN we are beginning to get some coordinated efforts to follow up on suspicious objects. Keep up the careful work to everyone involved. We had a great couple of weekends observing and I had a chance to increase my reference library of images. Sincerely, Wayne (aka Mr. Galaxy) Johnson
