0445 UTC - (N62.39 E159.32) - Shageluk, Alaska, USA 
           Comments: I haven't made many reports this winter but wanted to get
           in at least one or two more before the skies were too light.  Lucky
           me! A nice arc at 45 degrees with color bands at the east terminal
           end of the arc.  Not very bright but noticeable.   very faint glow
           of twilight can be seen northeast.

           Comments: Since nothing visible at 09:00, slept. Woke to an arc at
           25 degrees alt. at 13:00. Faint rays in NW. Mostly obscured by
           twilight by 13:15.
