SUNSPOT MONITORING – SEPTEMBER 18, 2017

992 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, September 18, 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. The lone visible sunspot group AR2680 has been quiet without any solar flaring activity as it still exhibits stable magnetic configuration.

Meanwhile, the vigorous AR2673 (not seen in this image) produced several solar flaring activity with accompanying coronal mass ejections (CME) from the Sun’s far side during the past 24-hour coverage period.

The latest sunspot number (based on visual count and Wolf number calculation) is 13.

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.
