Here are today’s solar images taken from Al Sadeem Observatory, November 10, 2020.
The sky was partly cloudy with moderate breeze which provided good transparency but average to poor seeing at the time these images were taken.
AR2781 (Modified Zurich/Mcintosh sunspot configuration: Dsi/beta) continues to gradually decay and has been inactive over the past 24 hours. Meanwhile, another active region is about to rotate into Earth-view from the far southeastern limb (encircled; un-numbered). The latest sunspot number (based on visual count and Wolf number calculation) is 19. Other visible solar features observed were small quiescent prominences along the northwestern and southwestern limbs, as well as the well-defined enhanced plages associated with the AR2781 and former AR2780 at the northwestern quadrant were distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to be at low levels with chances of solar flares of B-class to C-class intensity, mainly from AR2781. 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.
