The solar activity was low over the past 24 hours. The N0AA-AR 2771 is still on the disk. The X-ray flux was at A-class level and the solar activity is expected to remain low.

The Coronal Mass Ejection (CME) that took place on Aug 16th 18:00UT has a small chance of a glancing blow from late Aug 19th.

The greater than 10 MeV proton flux was at background levels over the past 24 hours. It is expected to stay at background levels for the next 24 hours. The greater than 2 MeV electron flux fluctuated between nominal and moderate levels over the past 24 hours. It is expected to remain nominal to moderate levels over the next 24 hours.

The solar wind speed near Earth varied between 280 and 340km/s (DSCOVR). The polarity of the Interplanetary Magnetic Field (IMF) was predominantly oriented away the Sun (phi angle in the positive sector). Bz fluctuated between -6 and +5 nT. The magnitude of the magnetic field varied between 1 and 7 nT. A negative coronal hole crossed the central meridian on August 17th. An enhancement could be expected on Aug 20th, possibly combined with any effects from the CME. For the first part of the next 24 hours, the solar wind speed is expected to remain low, while by the end of Aug 19th to be enhanced as a response to the influence of the CME.

The geomagnetic conditions were quiet. The values registered for the past 24 hours were 0-2 for K Dourbes and NOAA Kp. Quiet geomagnetic conditions are expected for the next 24 hours. The solar wind speed near Earth varied between 280 and 340km/s (DSCOVR). The polarity of the Interplanetary Magnetic Field (IMF) was predominantly oriented away the Sun (phi angle in the positive sector). Bz fluctuated between -6 and +5 nT.

An enhancement could be expected on Aug 20th, possibly combined with any effects from the CME. For the next 24 hours the solar wind speed is expected to remain low for the beginnig of that time period, while by the end of Aug 19th to be enhanced as a response to the influence of the CME.
