Here are today’s solar images taken from Al Sadeem Observatory, November 21, 2017.
The sky was clear with slight air turbulence making the seeing and transparency average to good at the time these images were taken.
Solar activity remains at very low levels over the past 24 hours. With the recent decay of AR2690, no sunspot groups were visible at the Sun indicating its relatively quiet state without any solar flaring recorded at this moment. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Some tiny prominences at the limbs and filaments and plages were 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.
