## Summary:
Solar activity was at high levels during this reporting period with 1 X-class flare, 53 M-class flares, and 15 C-type CMEs (see details below).
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 was estimated that the following CMEs were predicted to impact missions near Earth:

Geomagnetic activity was at strong levels with Kp index (a measure of geomagnetic activity, ranging 0-9) <= 7.33 for the reporting period. The geomagnetic storm lasted from 2026-07-04T00:00Z to 2026-07-04T18:00Z, with Kp values ranging from 5.67 to 7.33; the highest value of Kp = 7.33 occurred during the synoptic period of 2026-07-04T03:00Z to 2026-07-04T06:00Z (see notifications 20260704-AL-001, 20260704-AL-002, 20260704-AL-003, 20260704-AL-004). This enhancement in geomagnetic activity was associated with an interplanetary shock detected at L1 by SOLAR-1 at 2026-07-03T11:17Z which was likely associated with the arrival of the C-type CME first seen in GOES CCOR-1 at 2026-06-30T21:45Z and the CME arrival detected at L1 by SOLAR-1 at 2026-07-03T18:45Z which was likely associated with the arrival of the C-type CME first seen in SOHO LASCO C2 at 2026-07-01T12:12Z. This storm may have been further enhanced by an interplanetary shock detected at L1 by SOLAR-1 at 2026-07-04T12:00Z which was likely associated with the combined arrival of the S-type CME first seen in SOHO LASCO C2 at 2026-07-01T21:12Z and C-Type CME first seen in SOHO LASCO C2 at 2026-07-02T02:36Z.
The > 2.0 MeV energetic electron flux in the Earth's outer radiation belt crossed the threshold level of 1000 pfu starting at 2026-07-06T10:20Z (see notifications 20260706-AL-001, 20260706-AL-002). This elevation of energetic electron flux levels was likely associated with the arrivals of the C-type CME first seen in GOES CCOR-1 at 2026-06-30T21:45Z, the C-type CME first seen in SOHO LASCO C2 at 2026-07-01T12:12Z, and the combined arrivals of the S-type CME first seen in SOHO LASCO C2 at 2026-07-01T21:12Z and C-type CME first seen in SOHO LASCO C2 at 2026-07-02T02:36Z mentioned above. The energetic electron flux levels remained elevated through the end of the reporting period.
The energetic integral 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 above background levels starting late on 2026-07-03. These enhancements in solar energetic particles were likely associated with the M6.7 flare peaking at 2026-07-03T18:11Z from Active Region 14479 (N15W58) and the associated C-Type CME first seen in SOHO LASCO C2 at 2026-07-03T18:36Z as well as the M6.3 flare peaking at 2026-07-03T18:59Z from Active Region 14478 (S07W53) and the associated CME first seen in SOHO LASCO C2 at 2026-07-03T20:00Z. The proton fluxes returned to background levels by 2026-07-05 at GOES and 2026-07-07 at SOHO. The 13-100 MeV protons at STEREO A were at background levels for the entire reporting period.
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: 2026-07-08T00:00Z
## Outlook Coverage End Date: 2026-07-14T23:59Z
Solar activity is expected to vary between low and moderate levels during the outlook period. There are currently five numbered Active Regions on the Earth-facing disk. Active Region 14482 (S09E30) has produced M-class flare activity in the reporting and outlook periods, and may continue to produce similar levels of flaring activity during the outlook period.
Geomagnetic activity is expected to vary between low and moderate levels during the outlook period. Two coronal holes centered around N08W28 and S23E05 (as seen in available imagery from SDO/AIA 193) may reach geoeffective longitudes on or around 2026-07-08 and 2026-07-12, respectively. The enhanced energetic electron flux levels at GOES observed during the reporting period returned to background levels early in the outlook period on 2026-07-08.

Start time of the event: 2026-07-07T22:12Z.
Estimated speed: ~790 km/s.
Estimated opening half-angle: 41 deg.
Direction (lon./lat.): -56/21 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-07-07T22:12:00-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 this CME may affect Lucy (glancing blow), BepiColombo (glancing blow), Europa Clipper (glancing blow), and OSIRIS-APEX (glancing blow). The flank of the CME will reach Lucy at 2026-07-24T18:00Z, BepiColombo at 2026-07-09T03:00Z, Europa Clipper at 2026-07-11T13:00Z, and OSIRIS-APEX at 2026-07-11T08:00Z (plus minus 7 hours).
The simulation also indicates that the CME may have a glancing blow at NASA missions near Earth. Simulations indicate that the flank of the CME will reach NASA missions near Earth at about 2026-07-10T16:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 3-5 (below minor to minor).

## 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 2026-07-06T10:20Z.
The elevated energetic electron flux levels are likely caused by the arrival of CME with ID 2026-06-29T22:24:00-CME-001 and CME with ID 2026-06-30T21:45:00-CME-001 (see notifications 20260630-AL-001, 20260630-AL-008, 20260701-AL-001, and 20260701-AL-002). The combined arrival of the CMEs was detected at SOLAR-1 at 2026-07-03T11:17Z (see notification 20260703-AL-001).
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: 2026-07-06T10:20:00-RBE-001.
## Notes:
The arrival of the CMEs is associated with geomagnetic storm with ID 2026-07-04T00:00Z (see notifications 20260704-AL-001, 20260704-AL-002, 20260704-AL-003, and 20260704-AL-004). Simulations indicated that the magnetopause separating magnetospheric and solar wind plasma was close to the geosynchronous orbit starting at 2026-07-03T20:57Z (see notification 20260703-AL-006).
