SUNSPOT MONITORING – SEPTEMBER 24, 2017

Here are today’s solar images taken from Al Sadeem Observatory, September 24, 2017.

The sky was partly cloudy and experienced intermittent light breeze, making the seeing and transparency average at the time these images were taken.

As expected, solar activity was at very low levels over the past 24 hours. No significant flaring activity from the lone visible inactive sunspot group AR2681 was observed; though it slightly grew in structure but remains stable in magnetic configuration.

Meanwhile, becoming visible at the Sun’s eastern limb, the vigorous sunspot group AR2673 has been re-designated as AR2682. Some weak B-class solar flares and a slow-moving coronal mass ejection (CME) were recorded associated with this sunspot group. It decayed significantly and became much steady in magnetic configuration compared to its previous state (around 1st week of September) which minimized the probability of producing major solar flaring activity.

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.
