     All,
     
     Indeed some excitement this weekend, but unfortunately two false 
     alarms! 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
