		Space Environment Summary During the past 24 hours, solar activity was low. Four active sunspot regions were on the visible disk without M-class and above flare produced. Solar wind speed decreased to about 400 km/s. The geomagnetic field was quiet to unsettled. Published: 2026-07-17 00:30 UTC Forecaster: 040/012

		Space Environment Forecast Within the next three days, solar activity is expected to be mainly low with a slight chance for M-class flares. The geomagnetic field is expected to be quiet to unsettled. Published: 2026-07-17 00:30 UTC Forecaster: 040/012
