SUNSPOT MONITORING – MAY 30, 2020

989 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, May 30, 2020.

The sky was generally clear with intermittent calm winds which provided good transparency and seeing at the time these images were taken.

The Sun remained spotless over the past 24 hours, extending to its 28th consecutive day. The latest sunspot number (based on visual count and Wolf number calculation) is 0. The new (unnumbered) active region from the northeastern limb (encircled) was found to be less active than yesterday as it rotates into Earth-view over the past 24 hours. It seemed to only exhibit a relatively small (barely seen) sunspot with lots of surrounding faculae and gradually decaying in structure which indicates its solar flare activity to have subsided a bit at the moment.

Other than that, not much going on significantly with the Sun lately, except for exhibiting huge eruptive prominences at the limbs, and small plages and faculae associated with the unnumbered active region and another one at the far southeastern hemisphere were distinctively captured in H-alpha imagery.

Space weather agencies* forecast solar activity to remain at low levels with low to medium potential of multiple solar flare activities ranging between B-class to C-class intensity, mainly from the upper-mentioned active region. Close monitoring is being conducted by numerous space weather agencies for any significant development in the next 2-3 days.

Equipment used are Skywatcher 120mm refractor telescope with Baader filter and unmodified Canon EOS 1D Mark IV DSLR camera for visible imagery and Lunt H-alpha solar telescope and QHYCCDIII mono camera for H-alpha imagery, mounted on Skywatcher EQ6 Pro. 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.
