Good morning,

This is the data that has been processed for the time period 2100 to 2200HRS UTC, 10,23,1998.

Unusual signal bursts are indicated in the ULF region of 1 to 2 hz. This .gif has been band pass filtered to eliminate all frequencies above and below 1.1 to 1.3hz. A very interesting pattern is quite evident. This signal burst does not occur one hour before or one hour after the pictured event.

Enclosed is a sound file of one of the bursts in the center of the pic.
