Sun and Moon today (12th August)

The Sun today shown a single solar spot No 2670.

Below is the Moon


Over the past 24 hours solar activity has been very low. No significant
flares have been recorded. Active Region (AR) 2670 (Mcintosh class:Hsx;
Mag. type:Alpha) has been quiet. 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 with a low probability of C-class flares.
The solar wind speed has increased from around 400 to 600 km/s over the
past 24 hours. The total magnetic field strength has fluctuated around 10
nT. The Bz component fluctuated around 0 nT but was mainly positive,
ranging between -10 and +10 nT. Geomagnetic conditions ranged between Kp
index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours.
Several small low latitude coronal holes are currently in the Western
hemisphere of the Sun, and there has been a small increase in geomagnetic
conditions this morning as we encountered the sector boundary combined with
a negative Bz. Geomagnetic conditions are expected to be mainly quiet with
some short periods of activity.
