SUNSPOT MONITORING – JULY 20, 2020

1024 944 alsadeemadmin

Here is today’s white-light solar image taken from Al Sadeem Observatory, July 20, 2020.

The sky was mostly covered with light to mid-level clouds and intermittent moderate breeze which provided average to poor transparency and seeing at the time these images were taken. No H-alpha imagery was captured due to the obstruction of clouds.

The Sun remains generally spotless and inactive over the past 72 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 0. No significant flaring activity was recorded. The Sun has been at this state for about 9 days already.

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.
