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 (minor impact) and STEREO A (glancing blow). The leading edge of the CME may reach Parker Solar Probe at 2026-07-12T01:00Z and the flank of the CME may reach STEREO A at 2026-07-13T07:00Z (plus minus 7 hours).

Ensemble modeling update on CME with ID 2026-07-09T07:53:00-CME-001 (see previous notification 20260709-AL-001). Based on analysis by the Moon to Mars Space Weather Analysis Office and heliospheric ensemble modeling carried out at the Community Coordinated Modeling Center, it is estimated that the CME may impact STEREO A. For 42 ensemble members (see notes section), simulations indicate that the leading edge of the CME will reach:
- STEREO A between about 2026-07-12T09:00Z and 2026-07-12T11:42Z (average arrival 2026-07-12T10:38Z) for 7% of simulations.
Additionally the CME is estimated to reach NASA missions near Earth between about 2026-07-11T17:51Z and 2026-07-12T01:42Z (average arrival 2026-07-11T21:18Z) for 100% of simulations. The ensemble-based forecast indicates that there is a 96% chance for the maximum Kp index to be in the 5-7 range (minor to strong).

## Notes:
The CME event with ID 2026-07-09T07:53:00-CME-001 is also predicted to impact BepiColombo at 2026-07-10T08:40Z, Juice at 2026-07-13T18:59Z, Parker Solar Probe at 2026-07-11T05:35Z, OSIRIS-APEX at 2026-07-13T01:26Z (glancing blow), and Europa Clipper at 2026-07-13T10:00Z (glancing blow) (plus minus 7 hours) based on previous heliospheric modeling (see notification 20260709-AL-001).
This CME event (2026-07-09T07:53:00-CME-001) is associated with C2.7 flare from Active Region 14485 (S10W31) with ID 2026-07-09T06:51:00-FLR-001 which peaked at 2026-07-09T07:13Z.
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.

The simulation also indicates that the CME may impact NASA missions near Earth. Simulations indicate that the leading edge of the CME will reach NASA missions near Earth at about 2026-07-12T01:38Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 4-7 (below minor to strong).

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.

3: C-type CME detected by STEREO A / GOES.
Start time of the event: 2026-07-08T10:09Z.

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 CMEs may impact Mars (minor impact) and Psyche (minor impact). The combined leading edge of the CMEs will reach Mars at 2026-07-12T08:00Z and Psyche at 2026-07-12T06:00Z (plus minus 7 hours).

## Summary:
C-type CME detected by STEREO A / GOES / SOHO.
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).
