SUNSPOT MONITORING – SEPTEMBER 19, 2017

934 583 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, September 19, 2017.

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

As expected, very low solar activity continues over the past 24 hours. Still exhibiting stable magnetic configuration, the lone visible sunspot group AR2680 has been inactive without any solar flaring activity. Some of its trailer spots have already decayed.

The relatively energetic AR2676 is about to return into Earth-view, expected to give a slight boost in solar activity in the coming few days.

The latest sunspot number (based on visual count and Wolf number calculation) is 11.

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.
