Here are today’s solar images taken from Al Sadeem Observatory, August 15, 2020.
The sky was partly cloudy with intermittent light to moderate breeze which provided average to poor transparency and seeing at the time these images were taken.
Over the past 24 hours, AR2771 has already decayed into plage, leaving the Sun spotless and eased its activity at the moment. No significant flaring activity from the previous sunspot groups was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. The small remnant enhanced plages associated with the former active regions (including ex-AR2770 approaching the western limb), together with few quiescent and huge eruptive prominences mostly at the northwestern limb were distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to be 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. For H-alpha imagery, the equipment used are Lunt 60mm H-alpha solar telescope, and QHYCCD290III mono camera; all mounted on Skywatcher EQ6 pro mount 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.
