SUNSPOT MONITORING – JULY 13, 2020

Here are today’s solar images taken from Al Sadeem Observatory, July 13, 2020.

The sky was partly cloudy but with intermittent moderate to fresh breeze which provided average to poor transparency and seeing at the time these images were taken.

The Sun has been generally spotless and inactive over the past 48 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 0. No significant flaring activity was recorded. The Sun exhibited several huge eruptive prominences at the limbs mostly along the Sun’s the southwestern and southeastern limbs as the only noteworthy solar features visible 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.
