Here are today’s solar images taken from Al Sadeem Observatory, February 11, 2018.
The sky was clear with light air turbulence making the seeing and transparency good at the time these images were taken.
The lone visible sunspot group AR2699 continues to bring out several solar flares ranging from B-class to C-class intensity as it grew further in structure, especially on its intermediate and trailer spots over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 24. A potential new active region was seen developing at the Sun’s western hemisphere (encircled) and will be watched closely for any progress. Several tiny prominences, filaments, plages, and flaring activity from AR2699 were distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to remain at low levels with chances of B-class to C-class (possibly up to M-class) intensity 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 few days. Close monitoring is being conducted by numerous space weather agencies for any significant development.
