Here are today’s solar images taken from Al Sadeem Observatory, November 18, 2017.
The sky was mostly clear with slight air turbulence making the seeing and transparency average at the time these images were taken.
Both small and inactive sunspot groups AR2687 and AR2688 experienced quick structural decay as over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 23. Several tiny prominences were clearly on the limbs as well a huge dark filament rotating towards Earth-view at the southwestern portion of the Sun’s disk 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.
