SUNSPOT MONITORING – OCTOBER 10, 2020

988 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, October 10, 2020.

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

Both AR2774 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha) has decayed most of its structure, barely visible in white-light imagery. In contrast, AR2775 (Cro/beta) has developed more spots and expanded its sunspot coverage area. Both sunspot groups exhibit a generally weak magnetic structure and currently quiet.  No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 26. Small enhanced plages associated with the upper mentioned sunspot regions, a short stable filament at the far northern hemisphere, and some moderately huge eruptive prominences at the 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.
