SUNSPOT MONITORING – OCTOBER 5, 2018

1024 944 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, October 5, 2018.

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

The lone visible sunspot group AR2723 (Modified Zurich/McIntosh sunspot classification: Axx/alpha) has decayed further in spot structure, barely seen in both visible and H-alpha imagery as it approaches the western limb. No significant flaring activity associated with this active region has been recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 11.  Other solar features include several small filaments and plages associated with the decaying AR2723 across the disk, and hook-shaped prominences at the southwestern limb as 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. Close monitoring is being conducted by numerous space weather agencies for any significant development.
