## Summary:
Solar activity was at moderate levels during this reporting period with 2 M-class flares, 1 O-type CME, and 14 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:
CME Starting time | Predicted Impacts (plus minus 7 hours)
-----------------------------------------------------------------------------
2026-05-10T13:48Z NASA missions near Earth at at 2026-05-13T14:00Z (glancing blow), Kp index 2-4 (below minor)
(see notification 20260510-AL-004).
The arrival of this CME was likely detected at L1 around 2026-05-13T07:22Z. The arrival of this CME is under investigation.
It was also estimated that the following CMEs were predicted to impact the listed locations:

Geomagnetic activity was at below minor levels with Kp index (a measure of geomagnetic activity, ranging 0-9) <= 3.33 for the reporting period.
The > 2.0 MeV energetic electron flux detected at GOES remained below the threshold level of 1000 pfu for the entire reporting period.
The energetic proton flux of >10 MeV protons detected at GOES and the 13-100 MeV protons at STEREO A were all at background levels for the entire reporting period.
Space Weather Impact:
Space weather impacts on NASA spacecraft are expected to have been low this reporting period.

## Space Weather Outlook:
## Outlook Coverage Begin Date: 2026-05-13T00:00Z
## Outlook Coverage End Date: 2026-05-19T23:59Z
Solar activity is expected to vary between low to moderate levels during the outlook period. There are currently four numbered Active Regions on the Earth-facing disk. Active Region 14436 (N18E16) produced M-class flaring over the reporting period and may produce similar levels of flaring activity during the outlook period.
Geomagnetic activity is expected to vary between low to moderate levels during the outlook period. A coronal hole (as seen in available EUV imagery from SDO/AIA 193) centered around N05W05 may become geoeffective on or around 2026-05-15.

## Summary:
Significant interplanetary shock detected by ACE and DSCOVR at L1 at 2026-05-13T07:22Z.
The shock may be associated with the CME with ID 2026-05-10T13:48:00-CME-001 (see notification 20260510-AL-004) and the arrival of a coronal hole high speed stream. Some magnetospheric compression is expected and a minor geomagnetic storm is possible.
Activity ID: 2026-05-13T07:22:00-IPS-001.
## Notes: This arrival signature is still developing and the cause of this event is under analysis.

## Summary:
C-type CME detected by GOES / SOHO.
Start time of the event: 2026-05-12T15:24Z.
Estimated speed: ~762 km/s.
Estimated opening half-angle: 13 deg.
Direction (lon./lat.): 78/7 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-05-12T15:24:00-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 Juice (glancing blow), Parker Solar Probe (glancing blow), and STEREO A (glancing blow). The flank of the CME will reach Juice at 2026-05-18T06:00Z, Parker Solar Probe at 2026-05-14T03:00Z, and STEREO A at 2026-05-15T16:00Z (plus minus 7 hours).
