No sunspot monitoring post was issued yesterday (August 27, 2020) due to unfavorable weather conditions (overcast sky with strong winds and light rains brought by a brief thunderstorm event).
The sky was mostly clear with calm breeze which provided good transparency and seeing at the time these images were taken.
The Sun remains generally spotless and inactive on its 7th consecutive day. The latest sunspot number (based on visual count and Wolf number calculation) is o. Nothing much significant going on with the Sun lately except for several small quiescent prominences at the limbs, few stable mound filaments at the far southern hemisphere, and a scattered disintegrating plage which recently rotated from the northeastern limb as the only noteworthy solar features distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to remain 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.
