Here are today’s solar images taken from Al Sadeem Observatory, August 6, 2021.
The sky was generally clear with light to moderate breeze which provided good transparency and seeing at the time these images were taken.
Solar activity has remained at very low levels over the past 24 hours. The Sun is currently spotless after the quick decay of previously designated AR2851 and AR2852 and departing AR2850. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0.
Enhanced plages associated with the upper-mentioned former sunspot groups and some moderately huge eruptive prominences mainly at NW and SW limbs were distinctively captured in H-alpha imagery.
Space weather agencies* forecast very low solar activity of only B-class solar flares in the next few days. 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 QHYCCD 290III 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.
