Here are yesterday’s solar images taken from Al Sadeem Observatory, September 28, 2017.
The sky was clear but experienced intermittent light to moderate winds, making the seeing and transparency average at the time these images were taken.
Very low solar activity was observed over the past 24 hours. As expected, the three visible active regions AR2681, AR2682 and AR2683 remain relatively stable in magnetic configuration and did not emanate any major produce flaring activity. A couple of small sunspots were seen popping out from AR2682 which could indicate a slight upsurge in solar activity from this sunspot group.
The latest sunspot number (based on visual count and Wolf number calculation) is 42.
Space weather agencies* forecast 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.
