"Tweeks" och visslare; två typer av dispersioner
01 April 1994, 1130 UT/0330 PST, 100 mi. north of San Francisco, CA in Mendocino Co. (Fish Rock Road 20 mi. west of Ukiah). Clusters of nearly pure whistlers occurred all night and were quite beautiful! This segment has many whistlers of varying strength. I really like this segment of the tape for its nice mix of whistlers and tweeks.
