Here are today’s solar images taken from Al Sadeem Observatory, September 12, 2018.
The sky was clear with light air turbulence making the seeing and transparency good at the time these images were taken.
Over the past 24 hours, the newly designated AR2722 (Zurich/Mcintosh sunspot classification: Axo/ beta magnetic configuration) has lost some of its trailer spots after its brief development and is currently inactive. The latest sunspot number (based on visual count and Wolf number calculation) is 13. Associated plages of AR2722 and former AR2721 near the western limb, as well as few eruptive prominences at the limbs were distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to be at low levels with chances of weak X-ray fluxes or flares ranging up to B-class (possibly isolated C-class) intensity, mainly from AR2722. 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.
