Here are today’s solar images taken from Al Sadeem Observatory, August 17, 2018.
The sky was clear with light air turbulence making the seeing and transparency good at the time these images were taken.
The lone visible sunspot group AR2718 produced a weak A-class flare based on space weather agency records. Other than that, no other significant flaring activity was recorded. Its trailer spots have decayed in structure. The latest sunspot number (based on visual count and Wolf number calculation) is 11. Few receding prominences at the limbs, small filaments and plage associated with AR2718 were distinctively captured 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.
