One of a host of spectacular spread-F events captured by
the Jicamarca Radio Observatory's big radar. The turbulent filaments

Here is a portion of a night of spread-F that has appeared
in a number of publications, although never in color to my knowledge.
(The additional time intervals have had little exposure, let alone
never been published.)
