SUNSPOT MONITORING – DECEMBER 21, 2017

No sunspot monitoring information was issued yesterday, December 20, 2017 due to some important institution-related errands.

Here are today’s solar images taken from Al Sadeem Observatory, December 21, 2017.

The sky was clear with light air turbulence making the seeing and transparency good at the time these images were taken.

Solar activity remains at very low levels over the past 24 hours. The recently designated sunspot group AR2692 grew more bipolar sunspots and produced some weak B-class flares throughout the course. Despite its gradual development, it is currently stable in magnetic complexity at this moment. The latest sunspot number (based on visual count and Wolf number calculation) is 21. Other features such as small prominences and filaments were distinctively captured in H-alpha imagery.

Space weather agencies* forecast solar activity to remain low with chances of B-class to possibly C-class flares. 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.
