Here are today’s solar images taken from Al Sadeem Observatory, January 27, 2021.
The sky was mostly clear with intermittent moderate breeze which provided good transparency but average seeing at the time these images were taken.Â
Solar activity has been at very low levels over the past 24 hours. After AR2799 departed from Earth-view, the lone visible designated sunspot group AR2797 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha) has further decayed in structure and remained stable. Meanwhile, a new developing bipolar active region was seen emerging at the mid-northern hemisphere (encircled). The latest sunspot number (based on visual count and Wolf number calculation) is 13.Â
Other solar features observed were several minor plasma ejections through the presence of a few small quiescent prominences particularly along the western side and some moderately huge ones along the eastern side, few short stable filaments across the Sun’s disk, and the enhanced plages associated with AR2797, and the undeveloped region at the northeastern quadrant and the newly emerging one as distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity gradual decrease in solar activity but still within low levels with chances of solar flares of up to B-class (possibly isolated C-class) intensity, mainly from AR2797. Close monitoring is being conducted by numerous space weather agencies for any significant development, especially from the emerging new developing active region.
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.
