A new study suggests that computers can learn to detect solar flares and other occurrences in vast streams of solar images, helping NOAA forecasters issue space weather alerts more in real-time. The machine-learning technique was improved by scientists at CIRES and…
MetService recorded nearly 100 000 lightning strikes in 24 hours over South Island, New Zealand, leading up to Saturday morning, December 7, 2019. Some of the strikes were associated with severe storms over Westland, the agency said. The West Coast has also been…
