Here are today’s solar images taken from Al Sadeem Observatory, June 20, 2020.
The sky was partly covered with cirrus clouds with intermittent light to moderate winds which provided average transparency and seeing at the time these images were taken.
The Sun is currently spotless and generally inactive over the past 24 hours on its 6th consecutive day. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Nothing much going on with the Sun lately except for exhibiting few moderately huge eruptive prominences at the opposite (northeastern and southwestern) limbs and the spotless small stable plage region at the Sun’s eastern quadrant 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 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.
