## Summary:
Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux is above 1000 pfu starting at 2026-06-13T12:45Z.
The elevated energetic electron flux levels are caused by the arrival of a coronal hole high speed stream which started on 2026-06-11, reaching a maximum speed of approximately 620 km/s. The solar wind speed observed at L1 is currently around 610 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.

## Summary:
Ensemble modeling update on CME with ID 2026-06-12T16:36:00-CME-001 (see previous notification 20260612-AL-001).
Based on heliospheric ensemble modeling carried out at the Moon to Mars Space Weather Analysis Office, it is estimated that the CME may impact NASA missions near Earth. Out of 36 ensemble members (see notes section), 36 (100%) indicate impact at NASA missions near Earth. Ensemble simulations indicate that the leading edge of the CME will reach NASA missions near Earth between about 2026-06-14T09:32Z and 2026-06-15T04:11Z (average arrival 2026-06-14T18:01Z). The ensemble-based forecast indicates that there is a 80% chance for the maximum Kp index to be in the 5-7 range (minor to strong).

## Notes:
The CME event with ID 2026-06-12T16:36:00-CME-001 is also predicted to impact BepiColombo at 2026-06-13T16:14Z, Europa Clipper at 2026-06-16T05:10Z, OSIRIS-APEX at 2026-06-15T09:18Z, and Juice at 2026-06-16T12:00Z (Glancing Blow) (plus minus 7 hours) based on previous heliospheric modeling (see notification 20260612-AL-001).
Ensemble CME modeling at M2M is performed by building sets of initial CME parameters and carrying out separate simulations for each set. This approach allows a mapping of initial CME parameter uncertainties into a statistical characterization of CME arrival times and impact at locations of interest.
Description of links: For each location, the first link shows the WSA-ENLIL+Cone model animation for the median CME input parameters, the second link shows the probabilistic distribution of predicted arrival times histogram, and the third link shows a stack plot of the WSA-ENLIL+Cone modeled magnetic field, velocity, density, and temperature for all ensemble members. For missions near Earth, a histogram of the probabilistic Kp forecast is also provided.

Geomagnetic activity was at moderate levels with Kp index (a measure of geomagnetic activity, ranging 0-9) <= 6.33 for the reporting period. The highest value of Kp = 6.33 occurred during the synoptic period 2026-06-05T15:00Z to 2026-06-05T18:00Z (see notifications 20260605-AL-004, 20260605-AL-005). This enhancement in geomagnetic activity was associated with the interplanetary shock detected at L1 by ACE at 2026-06-05T04:23Z which was associated with the arrival of the O-type CME first seen in STEREO A COR2 at 2026-06-03T01:53Z and followed by a subsequent arrival of the O-type CME first seen in SOHO LASCO C2 at 2026-06-03T11:48Z.
The > 2.0 MeV energetic electron flux in the Earth's outer radiation belt crossed the threshold level of 1000 pfu starting at 2026-06-06T16:15Z (see notifications 20260606-AL-002, 20260606-AL-003, 20260608-AL-001). This elevation of energetic electron flux levels was likely associated with the arrivals of the O-type CME first seen in STEREO A COR2 at 2026-06-03T01:53Z and the O-type CME first seen in SOHO LASCO C2 at 2026-06-03T11:48Z. The energetic electron flux levels remained elevated through the end of the reporting period.
The energetic proton flux of >10 MeV protons at GOES as well as the flux of one or more of the >15.8 MeV proton channels at SOHO was elevated but below threshold starting on 2026-06-06. These slight enhancements in solar energetic particles were associated with the M1.8 flare peaking at 2026-06-06T14:01Z from Active Region 14461 and the associated O-type CME first seen in SOHO LASCO C2 at 2026-06-06T14:11Z. These fluxes subsided to near-background levels by the end of 2026-06-09.
The 13-100 MeV protons at STEREO A were at near background levels for the reporting period. A brief elevation was detected by STEREO A on 2026-06-05 through 2026-06-07. This elevation was likely associated with the C-Type CME first seen in SOHO LASCO C2 at 2026-06-05T09:09Z.
Space Weather Impact:
Space weather impacts on NASA spacecraft are expected to have been moderate this reporting period due to the elevated energetic electron flux in the Earth's outer radiation belt described above.

## Space Weather Outlook:
## Outlook Coverage Begin Date: 2026-06-10T00:00Z
## Outlook Coverage End Date: 2026-06-16T23:59Z
Solar activity is expected to vary between low and moderate levels during the outlook period. There are currently seven numbered Active Regions on the Earth-facing disk. Active Region 14455 produced two M-class flares and one X-class flare during the reporting period before rotating over the west limb on 2026-06-09. Active Region 14465 (N09E42) rotated onto the Earth-facing disk on 2026-06-07 and based on its current magnetic complexity may exhibit increased flaring activity through the outlook period.
Geomagnetic activity is expected to vary between low and moderate levels during the outlook period. A coronal hole centered around (N05W18) (as seen in available imagery from SDO/AIA 193) may reach geoeffective longitudes on or around 2026-06-10. The enhanced energetic electron flux levels at GOES observed during the reporting period have remained elevated and are anticipated to remain elevated through at least the first half of the outlook period (see notification 20260610-AL-001).

## 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 2026-06-10T16:15Z.
The elevated energetic electron flux levels observed since 2026-06-06T16:15Z (see notifications 20260606-AL-002, 20260606-AL-003, and 20260608-AL-001) are likely caused by the arrival of the CME with ID 2026-06-03T01:53:00-CME-001 (see notifications 20260603-AL-003, 20260603-AL-004, 20260603-AL-010, 20260603-AL-013, 20260603-AL-014) and the CME with ID 2026-06-03T11:48:00-CME-001 (see notifications 20260603-AL-011, 20260603-AL-013, 20260603-AL-014). The arrival of these CMEs was detected at L1 by ACE at 2026-06-05T04:23Z (see notification 20260605-AL-001) and 2026-06-05T12:06Z, respectively.
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: 2026-06-06T16:15:00-RBE-001.
## Notes:
The arrival of these CMEs were associated with a moderate geomagnetic storm with ID 2026-06-05T15:00:00-GST-001 (see notifications 20260605-AL-004 and 20260605-AL-005).
