SUNSPOT MONITORING – JULY 23, 2020

No sunspot monitoring was issued over the past 2 days, 2020, due to unfavorable weather conditions (sandstorm).

Here is today’s white-light solar image taken from Al Sadeem Observatory, July 23, 2020. No H-alpha imagery was taken due to poor seeing brought by strong upper-level winds.

The sky was slightly hazy with light to moderate breeze which provided average to poor transparency and seeing at the time these images were taken.

Over the past 3 days, space weather agencies has been monitoring the status of the lone visible sunspot group AR2767 (Modified Zurich/Mcintosh sunspot configuration: Hsx/alpha). Despite its relatively huge spot structure, it is generally inactive and magnetically stable with no significant flaring activity recorded.

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.
