## Community Coordinated Modeling Center Database Of Notifications, Knowledge, Information ( CCMC DONKI ) ## Message Type: Space Weather Notification - Continued Radiation Belt Enhancement ## ## Message Issue Date: 2026-05-22T15:50:17Z ## Message ID: 20260522-AL-002 ## ## Disclaimer: NOAA's Space Weather Prediction Center is the United States Government official source for space weather forecasts. This "Experimental Research Information" consists of preliminary NASA research products and should be interpreted and used accordingly. ## Summary: Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux remains elevated, recently crossing the threshold of 1000 pfu at 2026-05-22T10:25Z. The elevated energetic electron flux levels observed since 2026-05-16T15:20Z (see notifications 20260516-AL-003, 20260516-AL-004, 20260518-AL-001, and 20260520-AL-001) are caused by the arrival of a coronal hole high speed stream which started on 2026-05-15, reaching maximum sustained speeds of approximately 740 km/s. The solar wind speed observed at L1 is currently around 360 km/s. NASA spacecraft at GEO, MEO and other orbits passing through or in the vicinity of the Earth's outer radiation belt can be impacted. Activity ID: 2026-05-16T15:20:00-RBE-001. ## Notes: This coronal hole high speed stream is also associated with interplanetary shock with ID 2026-05-15T07:14:00-IPS-001 (see notification 20260515-AL-001) and geomagnetic storm with ID 2026-05-15T21:00:00-GST-001 (see notifications 20260516-AL-001, 20260516-AL-002).

## Community Coordinated Modeling Center Database Of Notifications, Knowledge, Information ( CCMC DONKI ) ## Message Type: Space Weather Notification - CME (Parker Solar Probe) ## ## Message Issue Date: 2026-05-22T13:51:46Z ## Message ID: 20260522-AL-001 ## ## Disclaimer: NOAA's Space Weather Prediction Center is the United States Government official source for space weather forecasts. This "Experimental Research Information" consists of preliminary NASA research products and should be interpreted and used accordingly. ## Summary: C-type CME detected by STEREO A / GOES / SOHO. Start time of the event: 2026-05-22T10:48Z. Estimated speed: ~594 km/s. Estimated opening half-angle: 28 deg. Direction (lon./lat.): 95/35 in Heliocentric Earth Equatorial coordinates. Activity ID: 2026-05-22T10:48:00-CME-001 Based on preliminary analysis by the Moon to Mars Space Weather Analysis Office and heliospheric modeling carried out at NASA Community Coordinated Modeling Center, it is estimated that the CME may impact Parker Solar Probe. The leading edge of the CME will reach Parker Solar Probe at 2026-05-23T18:09Z (plus minus 7 hours).

This cosmic snapshot covers a field of view over twice as wide as the full Moon within the boundaries of the high-flying constellation Cygnus. Made using astronomical narrowband filters, the image highlights the bright edge of a ring-like nebula traced by the glow of ionized hydrogen and oxygen gas. Embedded in the region's expanse of interstellar clouds, the complex, glowing arcs are sections of shells of material swept up by the wind from Wolf-Rayet star WR 134, the brightest star near image center. Distance estimates put WR 134 about 6,000 light-years away, making this telescopic frame over 100 light-years across. Shedding their outer envelopes in powerful stellar winds, massive Wolf-Rayet stars have burned through their nuclear fuel at a prodigious rate and end their final phase of massive star evolution in a spectacular supernova. Their stellar winds and final supernova explosion enrich the interstellar material with heavy elements to be incorporated in future generations of stars.
