SUNSPOT MONITORING – SEPTEMBER 29, 2020

Here are today’s solar images taken from Al Sadeem Observatory, September 28, 2020.

The sky was mostly clear with calm breeze which provided good transparency and seeing at the time these images were taken.

The small region of pores spotted yesterday at the southern hemisphere (barely visible in white-light imagery but its small enhanced plage is well-defined) has not fully developed in structure to be considered as a new sunspot group. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Other than that, not many significant going on with the Sun lately aside from few small quiescent prominences at the southwestern limb, short stable filaments, and the remnant scattered enhanced plages associated with former AR2773 and as the only noteworthy visible solar features 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. 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.
