Here are today’s solar images taken from Al Sadeem Observatory, September 5, 2017.
The sky was mostly clear but experienced intermittent light to moderate winds, making the seeing and transparency average at the time these images were taken.
The Sun remained dynamic with the current presence of five distinct active regions and high solar flaring activity. From the recent space weather reports*, over the past 24 hours, AR2673 has been developing progressively, magnetically unstable, and produced several moderately strong M-class flares which brought some slight radio and navigation satellite communication disruptions and bright aurorae across the polar regions. On the other hand, despite its large structure, AR2674 became less active as it only emitted a single low-level C-class flare. The remaining sunspot groups (departing AR2675 and AR2676, as well as AR2677) were still magnetically stable and inactive without any flaring activity recorded.
The latest sunspot number (based on visual count and Wolf number calculation) is 114.
With this stance, space weather agencies* predict further solar flaring activity (ranging from B-class to C-class with a moderate chance of M-class and possibly up to X-class; most likely from AR2673 or AR2674) in the next few days. 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.
