Here is today’s white-light solar image taken from Al Sadeem Observatory, August 11, 2020.
The sky was mostly covered with mid-level clouds and intermittent moderate breeze which provided poor transparency and seeing at the time these images were taken. No H-alpha imagery was captured due to the obstruction of clouds.
The lone visible sunspot group AR2770 (Modified Zurich/Mcintosh sunspot configuration: Brx/alpha) experienced further shrinkage in its sunspot structure. It was reported to have produced few minor B-class solar flares despite over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 12. No significant flaring activity was recorded.
Space weather agencies* forecast solar activity to remain at low levels with chances of weak X-ray fluxes or flares up to B-class (possibly up to C-class) intensity, mainly from AR2770. Close monitoring is being conducted by numerous space weather agencies for any significant development.
Equipment used are Skywatcher 120mm refractor telescope with Baader filter and unmodified Canon EOS 1D Mark IV DSLR camera for visible imagery. Pre-processing of visible solar images was performed in PIPP, stacking in Autostakkert, slight wavelet adjustments in Registax 6, and post-processing in Adobe Photoshop CC.
