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

The sky was partly cloudy (scattered at the western section of the sky) with intermittent light breeze which provided average transparency but good seeing at the time these images were taken.

AR2783 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha) has experienced slight decay in its structure, leaving only its leader spot, while approaching the southwestern limb. Few more trailer spots have emerged and grown in AR2785 (Ehi/beta)AR2787 exhibited very little to no change in its structure, still possessing a relatively simple magnetic configuration (Axx/alpha). These sunspot groups were generally quiet over the past 24 hours.

On the other hand, AR2786 (Fki/beta-gamma) has been consistently growing in structure, especially on its leader spots, and scattering and slight penumbral growth of its intermediate and trailer spots; expanding its coverage area of about 200,000km across. Several minor B-class and C-class flaring activities were recorded by the NOAA-SWPC and SIDC mainly from AR2786.

The latest sunspot number (based on visual count and Wolf number calculation) is 63. Other solar features observed were moderately huge eruptive prominences mostly at southeastern and southwestern 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 AR2786. 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.
