SUNSPOT MONITORING – SEPTEMBER 26, 2017

Here are today’s solar images taken from Al Sadeem Observatory, September 26, 2017.

The sky was clear but experienced intermittent light to moderate winds, making the seeing and transparency poor at the time these images were taken.

Some minor solar activity from the three visible active regions was recorded over the past 24 hours. The small sunspot groups AR2681 and AR2682 both produced sporadic B-class flares while a C-class solar flare was released courtesy of the larger newly-designated AR2683. These are relatively weak which will not cause any major disruptive effect on Earth.

The latest sunspot number (based on visual count and Wolf number calculation) is 39.

Space weather agencies* forecast low solar activity to continue with minimum solar flare activity, ranging up to C-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.
