SUNSPOT MONITORING -SEPTEMBER 23, 2017

Here are today’s solar images taken from Al Sadeem Observatory, September 23, 2017.

The sky was partly cloudy but with less air turbulence, making the seeing and transparency good 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 as it remains magnetically stable, though it grew slightly in structure.

Some extended solar flares were seen at the Sun’s limbs courtesy of the recently departed sunspot group AR2680 (western limb) and the returning vigorous AR2673; about to rotate towards Earth-view in the coming few days (eastern limb).

The latest sunspot number (based on visual count and Wolf number calculation) is 23.

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.
