Here are today’s solar images taken from Al Sadeem Observatory, August 4, 2020.
The sky was partly cloudy with intermittent light to moderate breeze which provided average to poor transparency and seeing at the time these images were taken.
Over the past 24 hours, both AR2771 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha) and AR2770 decayed its structure significantly and remained generally quiet. The latest sunspot number (based on visual count and Wolf number calculation) is 11. No significant flaring activity from both sunspot groups was recorded. The small remnant enhanced plages associated with the upper-mentioned sunspot groups, together with few huge eruptive prominences at the northwestern limbs were distinctively captured in H-alpha imagery.
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. For H-alpha imagery, the equipment used are Lunt 60mm H-alpha solar telescope, and QHYCCD290III mono camera; all mounted on Skywatcher EQ6 pro mount 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.
