Here are today’s solar images taken from Al Sadeem Observatory, January 16, 2021.
The sky was mostly clear with intermittent light to moderate breeze which provided good transparency but average seeing at the time these images were taken.
After 12 days of spotlessness, a new sunspot group has emerged in the Sun’s disk. The recently designated small sunspot group AR2796 (Modified Zurich/Mcintosh sunspot configuration: Cro/beta) experienced some scattering of its tiny spots but is generally inactive. No significant flaring activity was recorded throughout the monitoring period. The latest sunspot number (based on visual count and Wolf number calculation) is 15. Nothing much going on with the Sun lately aside from several minor plasma ejections through the presence of some small faint quiescent prominences at the limbs, and few short stable mound filaments at the far southern hemisphere as the other noteworthy solar features distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to be at low levels with chances of solar flares of up to B-class intensity, mainly from AR2796. 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.
