SUNSPOT MONITORING – SEPTEMBER 27, 2017

Here are yesterday’s solar images taken from Al Sadeem Observatory, September 27, 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.

As expected, low solar activity persisted over the past 24 hours. The large sunspot group AR2683 generated a relatively weak C-class flare while the other two AR2681 and AR2682 were inactive. These three sunspot groups were found to be magnetically stable which signifies little threat to any strong solar activity at this point.

The latest sunspot number (based on visual count and Wolf number calculation) is 36.

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.
