		Space Environment Summary During the past 24 hours, solar activity was low. Two active sunspot regions were on the visible disk without M-class or above flares produced. Solar wind speed decreased to about 310 km/s. The geomagnetic field was quiet. Published: 2026-07-19 00:30 UTC Forecaster: 039/022

		Space Environment Forecast Within the next three days, solar activity is expected to be mainly low with slight chance for M-class flares. The geomagnetic field is expected to be quiet to unsettled. Published: 2026-07-19 00:30 UTC Forecaster: 039/022
