Here are today’s solar images taken from Al Sadeem Observatory, April 8, 2020.
The sky was generally clear with intermittent light to moderate winds which provided good to average transparency and seeing at the time these images were taken.
The former AR2759 has been producing minor solar flares below B-class intensity over the past 24 hours, as per space weather agency records. The latest sunspot number (based on visual count and Wolf number calculation) is 0. The small disintegrating enhanced plage associated with the former AR2759, together with few tiny quiescent prominences at the limbs were distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to remain at low levels with chances of weak X-ray fluxes or flares ranging up to B-class intensity, mainly from former AR2759. 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.
