SUNSPOT MONITORING – SEPTEMBER 8, 2018

Here are today’s solar images taken from Al Sadeem Observatory, September 8, 2018.

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

A new small sunspot group has emerged at the near central portion of the Sun’s disk and recently designated as AR2721. No significant flaring activity associated with this active region (AR) was recorded as very low solar activity persisted over the past 24 hours. This will monitoring on its progress and its effect in solar activity in the next few days. The latest sunspot number (based on visual count and Wolf number calculation) is 13.  Some huge eruptive prominences at the opposite limbs, plages, and a tiny filament across the disk were distinctively captured 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 mainly from AR2721. 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.
