WAITING FOR SUMMER

Winter isn’t the best time to test lightning-detection equipment in Connecticut. We’ll have to wait a few more months before the circuits get a real workout. Jeff might have his set to trigger on the 30 or more hits per minute, but I suspect I’ll want to start thinking of alternatives at 2!

Considering how many of you live in southern states (or the Southern Hemisphere, for that matter), we’re sure a number of you will have the opportunity to thoroughly test all this under ideal conditions long before we will.

We invite you to let us know about your tales of discovery and what we can expect. Perhaps by next fall, we’ll have sufficient information for an update to the design.
