here are today’s solar images taken from Al Sadeem Observatory, May 22, 2020.
The sky was generally clear with intermittent moderate winds which provided good transparency but average seeing at the time these images were taken.
The Sun remained spotless and generally inactive over the past 24 hours extending to its 20th consecutive day. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Not much significant going on with the Sun lately except for a few tiny quiescent prominences at the limbs, and small remnant plages of the former active regions at the Sun’s opposite hemispheres, as the only noteworthy solar features 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 ranging 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 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.
