Space Weather Outlook:

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.
