From Kansas City, Mo (39 deg N)
Blue-green curtains seen 35 deg above horizon at around 3:15UT.
Many blue-green curtains observed between 4 &5 UT, some with
red flares towards the upper portions of the spikes. A friend in the
NE Texas Panhandle also described most of what I saw. Curtains seemed
to move slowly right to left.
