Recent NOAA Space Weather Prediction Center data show persistently quiet solar conditions throughout May 10–16, with subdued solar wind speeds near 400 km/s and low Kp indices that prevented any G3-level geomagnetic storms or stronger events. An isolated M5.8 flare from active region AR4436 on May 10 produced only an R2 radio blackout, falling short of the R3+ threshold required for market resolution, while no S3+ radiation storms were detected. This observational record aligns with trader consensus favoring zero major events at 99.5% implied probability. An unexpected X-class flare or high-speed stream from a coronal hole could still have triggered G3+ conditions in the final hours, though forecast models consistently limited impacts to G1 levels or below.

A G3 event is a geomagnetic storm with a classification indicating "Strong". An S3 event is a solar radiation storm with a "Strong" classification. An R3 event is a radio blackout event with a classification indicating "Strong". More information on the space weather classification criteria can be found here: https://www.swpc.noaa.gov/noaa-scales-explanation
This market may not resolve until the end of the relevant timeframe. This market will resolve according to the final number of qualifying events at the end of this market's timeframe to allow for revisions to the data. Only the initial report of an ongoing event with multiple reports will qualify, unless the rating of the event is upgraded to a qualifying level from a non-qualifying level within this market's timeframe.
If the reported data falls exactly between two brackets, this market will resolve to the higher range bracket.
This market will resolve based on information from the National Oceanic and Atmospheric Administration's Space Weather Prediction Center in the "ALERTS, WATCHES AND WARNINGS" table located under the heading titled "Current Space Weather Conditions" at https://www.swpc.noaa.gov/products/alerts-watches-and-warnings#.
If the resolution source becomes permanently unavailable, this market will resolve to the lowest bracket.
