SUNSPOT MONITORING – NOVEMBER 17, 2017

Here are today’s solar images taken from Al Sadeem Observatory, November 17, 2017.

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

Few days after AR2687 appeared, a new small sunspot group designated AR2688 has emerged in the Sun. Both active groups were found possessing relatively stable magnetic configuration which will not pose any significant flaring activity that could greatly affect Earth in the coming days. The latest sunspot number (based on visual count and Wolf number calculation) is 29. Several tiny prominences on the limbs and filaments 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.
