SUNSPOT MONITORING – JULY 15, 2017

Here are today’s solar images taken from Al Sadeem Observatory, July 15, 2017.

The sky was completely covered with haze/high clouds and experienced intermittent light to moderate breeze, making the seeing and transparency poor at the time these images were taken.

Gradual sunspot group structure decomposition was observed in both active regions AR2665 and AR2666 which brought some numerous B-class and C-class solar flare and radio bursts activity over the past 24 hours, which are minor and shall not affect Earth directly. Meanwhile, there was the late emergence of AR2667 at the Sun’s western limb, beside AR2666, which had rotated away from Earth view.

Due to generally unfavorable weather condition, only AR2665 is clearly visible in the images. The latest sunspot number (based on visual count and Wolf number calculation) is 40.

Space weather agencies forecast further solar flare activity (ranging from B-class to possible M-class) in the next couple of hours or days. Close monitoring is being conducted by numerous space weather agencies for any significant development.
