SUNSPOT MONITORING – APRIL 21, 2018

Here are today’s solar images taken from Al Sadeem Observatory, April 21, 2018.

The sky was clear with intermittent light breeze making the seeing and transparency average to good at the time these images were taken.

Currently possessing a bipolar (beta) magnetic configuration, the lone visible sunspot group AR2706 continues to gradually grow in structure and produced several B-class flares over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 16. Few tiny plages across the disk and prominences at the limbs were distinctively captured in H-alpha imagery.

Space weather agencies* forecast solar activity to remain relatively low with chances of continuity of isolated B-class (possibly up to C-class) solar flaring activity mainly from AR2706. 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.
