SUNSPOT MONITORING – NOVEMBER 16, 2020

Here are today’s solar images taken from Al Sadeem Observatory, November 16, 2020.

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

With the recent departure of AR2781 from Earth-view at the southwestern limb and the decay of AR2782, the Sun is currently spotless and generally quiet. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. The well-defined enhanced plages associated with the former AR2782 at the southern hemisphere and the returning AR2778 (also spotless) at the southeastern limb, as well as small quiescent prominences at the limbs and a short stable filament at the northern hemisphere, were also distinctively captured in H-alpha imagery.

Space weather agencies* forecast solar activity to be at very low levels with chances of solar flares of 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.
