## 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 2025-07-03T14:25Z.
The elevated energetic electron flux levels observed since 2025-06-27T11:40Z are caused by a coronal hole high speed stream starting on 2025-06-25, reaching a maximum sustained speed of approximately 775 km/s (see notifications 20250627-AL-001, 20250629-AL-002 and 20250701-AL-001). The solar wind speed observed at L1 is currently around 380 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:
Solar activity was at low levels during this reporting period. There were 2 O-type CMEs and 12 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 CME was predicted to impact missions near Earth:

It was also estimated that the following CMEs are predicted to impact the listed locations:

2025-06-25T06:36Z Juice at 2025-06-28T00:00Z (glancing blow) (see notification 20250625-AL-004).
2025-06-26T13:38Z Juice at 2025-06-29T00:00Z (glancing blow) (see notification 20250626-AL-001).
2025-06-27T12:12Z Juice at 2025-06-29T20:00Z (glancing blow), STEREO A at 2025-06-29T14:00Z (glancing blow) (see notification 20250627-AL-002).
2025-06-28T21:00Z OSIRIS-APEX at 2025-07-01T03:30Z, STEREO A at 2025-07-01T08:00Z (glancing blow) (see notifications 20250629-AL-001, 20250630-AL-002).
2025-06-29T12:12Z BepiColombo at 2025-06-30T23:00Z (glancing blow), Psyche at 2025-07-08T02:00Z (glancing blow) (see notifications 20250629-AL-003, 20250629-AL-004).
2025-06-29T15:36Z Solar Orbiter at 2025-07-02T12:00Z (glancing blow) (see notification 20250630-AL-001).
2025-06-30T15:48Z Solar Orbiter at 2025-07-03T06:00Z (glancing blow) (see notification 20250701-AL-002).
Geomagnetic activity was at minor levels with Kp index (a measure of geomagnetic activity, ranging 0-9) <=5.33 for the reporting period. The highest value of Kp = 5.33 occurred during the synoptic period of 2025-06-27T00:00Z-03:00Z. This enhancement in geomagnetic activity was associated with the interplanetary shock detected at L1 by DSCOVR and ACE at 2025-06-25T00:59Z which was likely associated with the arrival of a coronal hole high speed stream starting on 2025-06-25 (see notification 20250625-AL-003).
The > 2.0 MeV energetic electron flux in the Earth's outer radiation belt remained elevated above the threshold level of 1000 pfu due to a threshold crossing which occurred during the previous reporting period (see notifications 20250621-AL-004, 20250621-AL-005, 20250623-AL-001, 20250625-AL-002). This elevation of energetic electron flux levels observed since 2025-06-21T14:30Z was associated with the arrival at L1 detected by DSCOVR and ACE at 2025-06-19T07:00Z which was likely associated with the combined arrival of the C-type and O-type CMEs from 2025-06-15 in the previous reporting period. The energetic electron flux levels returned to background levels later on 2025-06-25. The >2.0 MeV energetic electron flux levels exceeded the threshold of 1000 pfu again at 2025-06-27T11:40Z (see notifications 20250627-AL-001, 20250629-AL-002, 20250701-AL-001). This subsequent elevation of energetic electron flux levels was associated with the arrival of a coronal hole high speed stream detected by DSCOVR and ACE at L1 on 2025-06-25. The energetic electron flux levels remained elevated through the end of the 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 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: 2025-07-02T00:00Z
## Outlook Coverage End Date: 2025-07-08T23:59Z
Solar activity is expected to vary between low and moderate levels during the outlook period. There are currently ten Active Regions on the Earth-facing disk. Active Region 14129 (N02E15) has produced low-level C-class flaring during the reporting period and may continue to produce flaring activity during the outlook period.
Geomagnetic activity is expected to vary between low and moderate levels during the outlook period. A coronal hole along the southern hemisphere of the Earth-facing disk, stretching from approximately longitudes E45 to W40 (as seen in available EUV imagery from SDO/AIA) may reach geoeffective longitudes starting around 2025-07-03. The energetic electron flux levels at GOES may remain elevated above background levels during the beginning of the outlook period.
