As this message is being written at the end of the day on June 15th, an intense display of noctilucent (night-shining) clouds is underway over Europe. Electric blue "NLCs" have been sighted as far south as France. The display may become visible over North America when night falls there. Favored viewing sites: Canada, Alaska and northern-tier US states--the same places where auroras are often seen. If you are located in the zone of visibility, and if you receive this message in time, go outside after sunset and look west for electric-blue tendrils spreading upward from the horizon.

Fluorscence resulting from increasingly-intense uhf radio emissions from Earth below. Radiation appears to be endless series of short bursts exchanged by pairs of point sources. Strong peak at 2.4gHz. Possibly communications among intelligent beings. Maybe not.
