Geomagnetic conditions were globally at active to moderate storm conditions (NOAA Kp 4 to 6), and locally at unsettled to minor storm conditions (K_BEL 3 to 5) during the past 24 hours. The disturbed geomagnetic conditions were due to the arrival of high speed streams (HSSs) from the large, positive polarity coronal hole (SIDC Coronal Hole 60). This coronal hole is extension of the southern polar coronal hole extending all across the solar equator (connected to equatorial SIDC Coronal Hole 82), and it started to cross the central meridian on Mar 22. In the next 24 hours, active to major storm conditions (K 4 to 7) are possible with the continuous arrival of HSSs from SIDC Coronal Holes
60, 82, and 96.
Earth is currently inside a very fast solar wind stream, due to the arrival of high speed streams (HSSs) from the large, positive polarity coronal hole (SIDC Coronal Hole 60). This coronal hole is extension of the southern polar coronal hole extending all across the solar equator (connected to equatorial SIDC Coronal Hole 82), and it started to cross the central meridian on Mar 22. Over the 24 hours, the solar wind speed increased from 360 km/s to 840 km/s and the interplanetary magnetic field ranged from 3 nT to 29 nT. The North-South component (Bz) ranged between -28 and 21 nT. Enhanced solar wind parameters are expected to continue until Mar 31 with the continuous arrival of HSSs from SIDC Coronal Holes 60, 82, and 96 (positive polarity).
