Here are today’s solar images taken from Al Sadeem Observatory, August 22, 2018.
The sky was mostly clear with light to moderate air turbulence making the seeing and transparency average at the time these images were taken.
Gradual structure decay was observed in the lone visible sunspot group AR2719. Still possessing a relatively stable bipolar-spot (beta) magnetic configuration, it did not produce any significant flaring activity over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 12. Space weather agencies reported a faint halo CME occurred on August 20th which is being investigated for any effect to Earth in the next few days. Few prominences at the limbs were also distinctively seen in H-alpha imagery.
Space weather agencies* forecast solar activity to remain at very low levels with chances of weak X-ray fluxes or flares ranging up to B-class intensity. The extent of the frequency and intensity of the Sun’s activity will highly depend on the magnetic flux fluctuations happening in the visible ARs in the coming days. Close monitoring is being conducted by numerous space weather agencies for any significant development.
