SUNSPOT MONITORING – NOVEMBER 27, 2020

Here are today’s solar images taken from Al Sadeem Observatory, November 27, 2020.

The sky was partly cloudy with intermittent light to moderate breeze which provided average transparency and seeing at the time these images were taken.

More active regions are emerging and growing. Sunspot groups AR2783 (Modified Zurich/Mcintosh sunspot configuration: Cso/beta) and AR2785 (Hsx/alpha) experienced slight umbral growth on its respective leader spots but were both generally quiet over the past 24 hours.

On the other hand, AR2786 has developed further in structure with growing trailer and intermediate spots, and much complex magnetic configuration (Fki/beta-gamma).

A small sunspot group has recently rotated into Earth-view from the northeastern limb which was recently designated as AR2787, currently possessing a relatively simple magnetic configuration (Axx/alpha).

Few more pores/enhanced solar regions were seen emerging near the two huge sunspot groups and another one rotating from the southeastern limb (encircled). Several minor C-class flaring activities and a non-Earth directed CME event at the northeastern limb were recorded by the NOAA-SWPC and SIDC mainly from AR2786 and AR2787.

The latest sunspot number (based on visual count and Wolf number calculation) is 56. Other solar features observed were moderately huge eruptive prominences at the western, northeastern, and southeastern limbs and some on-going magnetic enhancement/weak solar flarings within AR2786, as distinctively captured in H-alpha imagery.

Space weather agencies* forecast gradual increase in solar activity with chances of solar flares of B-class to C-class (possibly up to isolated M-class) intensity, mainly from the upper-mentioned sunspot groups. 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 QHYCCD 290III 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.
