SUNSPOT MONITORING – JULY 6, 2020

608 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, July 6, 2020.

The sky was mostly clear but with intermittent moderate winds which provided good transparency but average seeing at the time these images were taken.

The recently designated AR2766 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha) was found to be gradually decaying in structure after being designated last July 5, 2020. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 11. The Sun also exhibited some plasma ejection activities through the presence of few huge several huge elongated stable filaments at the Sun’s northern hemisphere and the disintegrating plages of AR2766 transiting the Sun’s disk as distinctively captured in H-alpha imagery.

Space weather agencies* forecast solar activity to remain 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. 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.
