Here are today’s solar images taken from Al Sadeem Observatory, December 9, 2020.
The sky was partly cloudy with intermittent moderate breeze which provided average transparency and seeing at the time these images were taken.
Space weather agencies* forecast solar activity to be at low levels with chances of solar flares from B-class up to C-class intensity, mainly from AR2790. 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.
