SUNSPOT MONITORING – MAY 28, 2020

1007 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, May 28, 2020.

The sky was mostly clear to partly cloudy with intermittent moderate winds which provided average transparency and seeing at the time these images were taken.

The Sun remained spotless and generally inactive over the past 24 hours, extending to its 26th consecutive day. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Space weather agencies reported few long-duration B-class flares from an active region at the far side of the Sun, about to rotate from the northeastern limb. Other than that, not much going on significantly with the Sun lately, except for exhibiting a few small quiescent prominences at the limbs, some mound filaments at the far northern hemisphere, and the disintegrating remnant plage of a former active region approaching the northwest limb.

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.
