SUNSPOT MONITORING – AUGUST 19, 2018

Here are today’s solar images taken from Al Sadeem Observatory, August 19, 2018.

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. Two active regions were currently visible in the Sun. First is AR2718 located at the near-central region which is decaying and the recently designated AR2719 (barely visible in white-light imagery, encircled) which is currently developing in structure located at the eastern portion of the Sun’s disk.  The latest sunspot number (based on visual count and Wolf number calculation) is 21. Both active regions were stable and no significant flaring activity associated was recorded.  Few eruptive hedgerow prominences and a huge filament at the northern hemisphere 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 (possibly up to C-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.
