It coincides with a large, positive cloud-to-ground lightning stroke
and has the features of the signal generated by lightning's initial surge, the researchers say.
Real-time lightning stroke
data from the NAPLN is provided seamlessly via the Internet within approximately 30 seconds from detection.
They interpret these signals as intracloud lightning strokes
related to, but not created by, the gamma-ray flash.
The topics include high-voltage switching equipment, substation integration and automation, shielding substations from direct lightning strokes
, the cyber security of substation control and diagnostic systems, and station commissioning and project closeout.
could stimulate people's brains and cause them to hallucinate bright blobs of light the same way a magnetic medical procedure does, two physicists propose in an upcoming Physics Letters A.
Aircraft soundings from the time of the event suggest little in the way of instabilit y over northern Illinois, and the lightning detection network failed to detect cloud-to-ground lightning strokes
Each person is shaved in about six lightning strokes
and the barber is not allowed to make more than ten individual cuts.
Other lightning detection networks rely on outdated satellite-based technology developed more than a generation ago and designed to detect only cloud-to-ground lightning strokes
