## Summary:
Ensemble modeling update on CMEs with IDs 2026-06-03T01:53:00-CME-001 and 2026-06-03T11:48:00-CME-001 (see previous notification 20260603-AL-013). 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 CMEs may impact STEREO A. For 27 ensemble members (see notes section), simulations indicate that the combined leading edge of the CMEs will reach:
- STEREO A between about 2026-06-04T21:46Z and 2026-06-05T18:16Z (average arrival 2026-06-05T09:59Z) for 88% of simulations.
Additionally the CMEs are estimated to reach NASA missions near Earth between about 2026-06-04T17:36Z and 2026-06-05T09:21Z (average arrival 2026-06-04T23:10Z) for 100% of simulations. The ensemble-based forecast indicates that there is a 63% chance for the maximum Kp index to be in the 5-7 range (minor to strong).

## Notes:
The CME events with IDs 2026-06-03T01:53:00-CME-001 and 2026-06-03T11:48:00-CME-001 are also predicted to impact Juice at 2026-06-06T11:49Z, OSIRIS-APEX at 2026-06-05T14:55Z, and Europa Clipper (Glancing Blow) at 2026-06-06T12:00Z (plus minus 7 hours) based on previous heliospheric modeling (see notification 20260603-AL-003,2 0260603-AL-004, 20260603-AL-010, 20260603-AL-011 and 20260603-AL-013).
This CME event (2026-06-03T01:53:00-CME-001) is associated with M9.3 flare from Active Region 14455 (N13W10) with ID 2026-06-03T01:22:00-FLR-001 which peaked at 2026-06-03T01:36Z (see notifications 20260603-AL-001, 20260603-AL-002).
This CME event (2026-06-03T11:48:00-CME-001) is associated with X1.0 flare from Active Region 14455 (N14W16) with ID 2026-06-03T11:19:00-FLR-001 which peaked at 2026-06-03T11:28Z (see notifications 20260603-AL-007, 20260603-AL-008).
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. For missions near Earth, a histogram of the probabilistic Kp forecast is also provided.

## Summary:
Solar activity was at moderate levels during this reporting period with 4 M-class flares, 1 O-type CME, and 16 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)
-----------------------------------------------------------------------------
2026-05-30T01:38Z NASA missions near Earth at at 2026-06-02T19:00Z (glancing blow), Kp index 2-3 (below minor)
(see notification 20260530-AL-002).
Analysis is ongoing to determine if the arrival of this CME was observed at L1 on 2026-06-03.
2026-06-02T17:23Z NASA missions near Earth at at 2026-06-05T08:00Z (minor impact), Kp index 3-5 (below minor to minor)
(see notification 20260602-AL-003).
It was also estimated that the following CMEs were predicted to impact the listed locations:

2026-06-01T19:00Z Mars at 2026-06-05T12:00Z (glancing blow), Psyche at 2026-06-05T12:00Z (glancing blow) (see notification 20260602-AL-001).
2026-06-01T19:09Z Mars at 2026-06-05T12:00Z (glancing blow), Psyche at 2026-06-05T12:00Z (glancing blow) (see notification 20260602-AL-001).
2026-06-02T17:00Z BepiColombo at 2026-06-03T12:00Z (glancing blow), Solar Orbiter at 2026-06-04T16:00Z (glancing blow), Juno at 2026-06-15T12:00Z (minor impact) (see notification 20260602-AL-002).
2026-06-02T17:23Z Europa Clipper at 2026-06-07T02:00Z (minor impact), OSIRIS-APEX at 2026-06-06T06:00Z (minor impact), Juice at 2026-06-07T18:00Z (glancing blow) (see notification 20260602-AL-003).
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.
The integral flux of the > 10 MeV protons at GOES, the flux of one or more of the >15.8 MeV protons channels at SOHO, and the flux of the 13-100 MeV protons detected at STEREO A were above background levels at the beginning of the reporting period but below each spacecraft's respective threshold due to the O-type CME first seen in SOHO LASCO C2 at 2026-05-25T22:12Z. These fluxes subsided to near-background levels by the end of 2026-05-28.
Later in the reporting period, the flux of 13-100 MeV protons detected at STEREO A increased above background levels but remained below the threshold of 10^-1 pfu/MeV on 2026-05-30. This relative increase is likely associated with the C-Type CME first seen in STEREO A COR2 at 2026-05-30T08:38Z. The energetic proton fluxes at STEREO A returned to background levels later on 2026-05-30 and remained at background levels alongside other observed fluxes through the end of the reporting period.
Space Weather Impact:
Space weather impacts on NASA spacecraft are expected to have been low to minor this reporting period due to the slightly elevated solar energetic particle fluxes described above.

## Space Weather Outlook:
## Outlook Coverage Begin Date: 2026-06-03T00:00Z
## Outlook Coverage End Date: 2026-06-09T23:59Z
Solar activity may vary between moderate and high levels during the outlook period. There are currently eight numbered Active Regions on the Earth-facing disk. Active Region 14455 (N13W16) produced three M-class flares during the reporting period and has produced two M-class flares and one X-class flare during the outlook period (see notifications 20260603-AL-001, 20260603-AL-002, 20260603-AL-005, 20260603-AL-006, 20260603-AL-007, 20260603-AL-008). This active region may continue to exhibit flaring activity through the outlook period.
Geomagnetic activity is expected to vary between low and moderate or severe levels during the outlook period. Potential increases in geomagnetic activity may be associated with the anticipated combined arrival of the three O-Type CMEs first observed in STEREO A COR2 at 2026-06-03T01:53Z, in STEREO A COR2 at 2026-06-03T07:23Z, and in SOHO LASCO C2 at 2026-06-03T11:48Z. These CMEs are predicted to impact missions near Earth around 2026-06-04T23:44Z (+- 7 hours) (see notification 20260603-AL-013). Additionally, a coronal hole centered around (N00W42) (as seen in available imagery from SDO/AIA 193) may reach geoeffective longitudes on or around 2026-06-03 and also be a source of increased geomagnetic activity during the outlook period.

## Summary:
Update on CMEs with IDs 2026-06-03T01:53:00-CME-001, 2026-06-03T07:23:00-CME-001, and 2026-06-03T11:48:00-CME-001 (see previous notifications 20260603-AL-003, 20260603-AL-004, 20260603-AL-009, 20260603-AL-010, and 20260603-AL-011). 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 affect Juice, OSIRIS-APEX, STEREO A, and Europa Clipper (glancing blow). The combined leading edge of the CMEs will reach Juice at 2026-06-06T11:49Z, OSIRIS-APEX at 2026-06-05T14:55Z, and STEREO A at 2026-06-05T13:58Z (plus minus 7 hours). The combined flank of the CMEs will reach Europa Clipper at 2026-06-06T12:00Z (plus minus 7 hours).
The simulation also indicates that the CMEs may impact NASA missions near Earth. Simulations indicate that the combined leading edge of the CMEs will reach NASA missions near Earth at about 2026-06-04T23:44Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 6-8 (moderate to severe).

Activity ID: 2026-06-03T07:23:00-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 Europa Clipper (glancing blow), Juice (glancing blow), OSIRIS-APEX (glancing blow), and STEREO A (glancing blow). The flank of the CME may reach Europa Clipper at 2026-06-08T18:00Z, Juice at 2026-06-08T00:00Z, OSIRIS-APEX at 2026-06-06T16:00Z, and STEREO A at 2026-06-06T12:00Z (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 2026-06-06T15:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 2-4 (below minor).
