Here are today’s solar images taken from Al Sadeem Observatory, June 2, 2020.
The sky was generally clear with intermittent light to moderate winds which provided good transparency but average seeing at the time these images were taken.
Space weather agencies have recently designated the small sunspot group at the northeastern section of the Sun’s disk as AR2764. It was the source of a strong M-class solar flare that occurred on May 29 but it has remained quiet and gradually decaying in structure over the past 2-3 days since it rotated into Earth-view, only exhibiting a barely seen tiny unipolar sunspot (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha). The latest sunspot number (based on visual count and Wolf number calculation) is 11. Other than that, the Sun exhibited a huge eruptive prominence at the northwestern limb, and small plages and faculae associated with AR2764, 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, mainly from AR2764. 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.
