SUNSPOT MONITORING – SEPTEMBER 20, 2017

Here are today’s solar images taken from Al Sadeem Observatory, September 20, 2017.

The sky was clear but experienced light to freeze breeze, blowing some dust, making the seeing and transparency poor at the time these images were taken.

As expected, low solar activity was observed over the past 24 hours. The previously designated sunspot group AR2676 was seen rotating towards Earth-view and spawned few weak B-class solar flares. On the other hand, the magnetically stable AR2680 remains inactive without any associated solar flaring activity recorded.

The latest sunspot number (based on visual count and Wolf number calculation) is 22.

Space weather agencies* forecast very 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.
