SUNSPOT MONITORING – NOVEMBER 19, 2017

992 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, November 19, 2017.

The sky was partly cloudy with slight air turbulence, making the seeing and transparency average at the time these images were taken.

Solar activity remains at very low levels with no significant flaring activity recorded over the past 24 hours. Small sunspot groups AR2687 and AR2688 (barely seen in white-light image) have further decayed in structure and inactive. The latest sunspot number (based on visual count and Wolf number calculation) is 12. A large eruptive prominence in the northwestern eastern and a huge filament in the southeastern portion were well-defined on the Sun’s disk in H-alpha imagery.

Space weather agencies* forecast solar activity to remain at very low levels with chances of weak X-ray fluxes or flares ranging up to B-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.
