ADDITIONAL COMMENTS: Met with Dave Dunham, who is in Houston on business and for the IOTA annual meeting. Loaned him a C-8, radio and tape recorder from Marg Nunez, and we drove up I-45 North to sites. A cold front had just moved thru just a few hours prior and cleared the skies. David set up just inside the southern limit and I set up 1/3 path width inside the southern limit.

Communicated with Ed Vinson and Wayne Hutchinson during the 3 hour drive and we finalized our positions. Skies were clear with some dew formation.
Setting up on a warm car hood eliminated dew formation for me !

Disappearance and reappearance were instantaneous, with no visible dimming. No visible blinks were observed during the 5 minute window surrounding the event.

Time reductions were done watching video visually frame by frame and computer stopwatch program.
