SUNSPOT MONITORING – APRIL 28, 2018

Here are today’s solar images taken from Al Sadeem Observatory, April 28, 2018.

The sky was partly cloudy with light to moderate air turbulence making the seeing and transparency average to poor at the time these images were taken.Solar activity remains at its relatively quiet state over the past 24 hours. As of capture time, the lone visible sunspot group AR2706 has completely decayed its sunspot structure, as depicted in visible imagery. Its associated plage and filament were still visible in H-alpha imagery. The latest sunspot number (based on visual count and Wolf number calculation) is 10. Nothing much happening except for some tiny prominences at the limbs as 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. Close monitoring is being conducted by numerous space weather agencies for any significant development.
