NOTE: the above forecasts are valid from 1230UT, 21 May 2019 until 23 May
2019
COMMENT: Over the past 24 hours solar activity has been low. The visible
solar disc was spotless and the X-ray flux remained below B-class level. No
Earth directed Coronal Mass Ejections (CMEs) have been detected. The
greater than 10MeV proton flux remained at background levels over the past
24 hours. Solar activity is expected to remain low over the next 24 hours.

The solar wind speed has fluctuated between 355 and 450 km/s over the past
24 hours. The total magnetic field strength fluctuated around 5 nT for much
of the period, with a minimum of 0.6 nT and a maximum of 7.1 nT recorded.
The Bz component was predominantly positive and ranged between -4.8 and
+7.1 nT.

Geomagnetic conditions have been quiet to unsettled over the past 24 hours,
with Kp index (NOAA) and local K index (Dourbes) ranging between 1-2 and
1-3, respectively. Quiet to unsettled geomagnetic conditions are expected
to continue over the next 24 hours, due to the weak solar wind stream
associated with the patchy negative polarity equatorial coronal hole which
began to traverse the central meridian on 18 May.
