SUNSPOT MONITORING – SEPTEMBER 13, 2018

1020 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, September 13, 2018.

The sky was clear with some light breeze making the seeing and transparency average at the time these images were taken.

The lone visible sunspot group AR2722 has decayed further in sunspot structure into a region of plage, barely seen in visible imagery and it was inactive. The latest sunspot number (based on visual count and Wolf number calculation) is 11.  Several huge eruptive prominences, mostly at the northwestern limb, and associated plages of AR2722 and another one recently rotated into Earth-view at the eastern limb 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.
