SUNSPOT MONITORING – AUGUST 25, 2018

Here are today’s solar images taken from Al Sadeem Observatory, August 25, 2018.

The sky was mostly clear with some passing thin high cirrus clouds and light to moderate air turbulence making the seeing and transparency average at the time these images were taken.

Based on space weather agency records*, few minor B-class flares were recorded from the two visible sunspot groups, decaying AR2719 and the rapidly growing AR2720. The latest sunspot number (based on visual count and Wolf number calculation) is 27. Few eruptive prominences at the limbs, a fairly large filament at the Sun’s northern hemisphere, and some eruptive prominences at the limbs 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 (possible up to isolated C-class) intensity, mainly from the two upper-mentioned active regions (ARs). 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.
