Solar wind measured at the L1 point, about 1.5 million km sunward of Earth, 30 to 60 minutes before it reaches us. Source: NOAA SWPC (DSCOVR / ACE). Every number carries the time NOAA observed it.

Space Weather Tracker indicator from the readings below. Not an official NOAA alert: see NOAA alerts.
Typical quiet solar wind.
Thin plasma, typical of fast streams.
Typical solar wind push on the magnetosphere (about 1.5 to 3 nPa).
Field points north: weak coupling with Earth.
Typical field strength.
Sideways field components (GSM). Direction only: Bz is what couples with Earth.
From L1 to Earth at the current speed.
Unbroken time with Bz below 0 nT (5-minute smoothing). At −5 nT or lower: 0 min. How long it lasts matters more than a single reading.

This is the solar wind now; the planetary Kp index is a 3-hour summary. See the Kp index and the aurora forecast.
