Here are today’s solar images taken from Al Sadeem Observatory, September 10, 2020.
The sky was clear with intermittent light to moderate breeze which provided good transparency but average seeing at the time these images were taken.
The Sun remains spotless and generally inactive on its 20th consecutive day. No significant flaring activity was recorded over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Nothing much going on with the Sun lately except exhibiting several small quiescent prominences at the limbs and the decaying remnant plage at the far southern hemisphere as distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to be at very low levels with chances of weak X-ray fluxes or flares up to B-class intensity. 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.
