Captured four upward lightning flashes around 130 am on 5/24/10. The first three where from the KEVN tower and the last was from the KNBN tower. All were single upward leader flashes.
Lightning is one of Nature's most spectacular displays. I document lightning with high-speed cameras and electromagnetic sensors to better understand this phenomenon. My current focus is on Upward Lightning which initiates from the tip of tall objects and propagates upward towards the clouds above.
