Here are today’s solar images taken from Al Sadeem Observatory, October 30, 2020.
The sky was generally clear with intermittent moderate breeze which provided good transparency but average to poor seeing at the time these images were taken.
Both AR2778 (Modified Zurich/Mcintosh sunspot configuration: Eao/beta) and AR2779 (Cai/beta) experienced gradual decay in its respective sunspot structures and magnetic complexity over the past 24 hours. Despite this change, both sunspot groups continued to produce some more minor B-class to C-class solar flares based on the recent space weather agency reports. The latest sunspot number (based on visual count and Wolf number calculation) is 29. Prominence activities at the Sun have subsided at the moment, as seen by the lack of visible prominences visible at the limbs; together with enhanced plages associated with AR2778 and AR2779, and a shallow elongated stable filament at the far northern hemisphere were distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to be at low levels with chances of B-class to C-class (possibly to isolated M-class) solar flare intensity, mainly from AR2778 and AR2279. 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.
