## Summary:

Solar activity was at low levels during this reporting period with 3 O-type CMEs and 21 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 the listed locations:

Geomagnetic activity was at below minor levels with Kp index (a measure of geomagnetic activity, ranging 0-9) <=4.33 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.

Solar energetic particle event detected by STEREO A. The flux of 13-100 MeV protons exceeded 10^(-1) pfu/MeV starting at 2025-10-22T00:09Z (see notifications 20251022-AL-001, 20251022-AL-003). The flux of one or more of the >15.8 MeV proton channels at SOHO and the energetic proton flux of >10 MeV protons detected at GOES were elevated at the beginning of the reporting period and remained below their respective thresholds before returning to background levels by 2025-10-25. These enhancements in solar energetic particles were associated with the O-type CME first seen in SOHO LASCO C2 at 2025-10-21T20:24Z in the previous reporting period (see notifications 20251021-AL-002, 20251022-AL-002).

Space Weather Impact:
Space weather impacts on NASA spacecraft are expected to have been moderate this reporting period due to the solar energetic particle event described above.

## Space Weather Outlook:
## Outlook Coverage Begin Date: 2025-10-29T00:00Z
## Outlook Coverage End Date: 2025-11-04T23:59Z

Solar activity is expected to vary between low and moderate levels during the outlook period. There are currently six Active Regions on the Earth-facing disk. Active Region 14262 (S14W83) has been the source of low-level C-class flaring during the reporting period 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. The energetic electron flux levels at GOES may be elevated above background levels during the outlook period due to a coronal hole high speed stream detected by ACE at L1 starting on 2025-10-28.
