Here are today’s solar images taken from Al Sadeem Observatory, September 26, 2020.

The sky was mostly clear with intermittent moderate to fresh breeze which provided good transparency but average seeing at the time these images were taken.

AR2773, despite struggling to exhibit a distinct sunspot structure (barely visible in white-light imagery) from a quick episode of sunspot re-development and decay, a minor C-class solar flare was produced from this sunspot region over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 11. Other than that, not many significant going on with the Sun lately aside from few small quiescent prominences at the limbs, as the enhanced plages associated with AR2773 as 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 (possibly up to isolated C-class) intensity, mainly from AR2773. 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.
