Observers: Ralph D'Andrea, Carina D'Andrea
Location: Grand Junction, Colorado
Date: March 19, 1997 11:45, 11:30 UT

First image taken 3/19, approximately 4:45 AM MST. Kodak Royal Gold 400, 1-1/2 min guided exposure, 52mm f/1.8 lens stopped to f/2.8. Second image is a 2 minute guided exposure, 4:30 AM MST, Kodak Royal Gold 400, 50mm f/1.8 lens stopped down to f/2.8

Location Grand Junction, Colorado, USA, approximately 3/4 mi. N of the west end of Walker Field Airport runway 29. Geological feature at bottom of frame is the Bookcliffs, slightly illuminated by the tower beacon.

We were fortunate enough to get a meteor in the image, below the comet. Two of us had our shutters open at this time. We are reasonably certain that the trail is not an airplane, as the two exposures were of different lengths, yet the trail is the same length on each image. I was busy guiding so I did not see a meteor personally. However, close inspection does not reveal the typical pulsation associated with an aircraft strobe in a time exposure. The other photographer (my 14-year-old daughter) did not personally notice the meteor, although she says she definitely did not see any aircraft.
