No sunspot monitoring posts were issued for the past 2 days (August 20-21, 2020) due to unfavorable weather (mostly cloudy sky) conditions.
Here are today’s solar images taken from Al Sadeem Observatory, August 22, 2020.
The sky was generally partly cloudy with intermittent moderate breeze which provided average to poor transparency and seeing at the time these images were taken.
Over the past 72 hours, AR2770 has decayed completely in structure and recently departing from Earth-view, which leaves the Sun currently spotless. The latest sunspot number (based on visual count and Wolf number calculation) is 0. A minor B-class solar flare was reported by SIDC yesterday which occurred at the far side of the Sun.
Space weather agencies* forecast solar activity to be at very low levels with chances of weak X-ray fluxes or flares up to B-class intensity. 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.
