Here are today’s solar images taken from Al Sadeem Observatory, June 13, 2020.
The sky was generally clear but intermittent moderate winds which provided good transparency but average seeing at the time these images were taken.
The lone visible sunspot group AR2765 (Modified Zurich/Mcintosh sunspot configuration: Hsx/alpha) was generally stable, gradually shrinking in structure, and inactive over the past 24 hours. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 11. Small disintegrating plages associated with AR2765 and few quiescent prominence activities at the limbs (including a huge mound eruptive one at the northwestern limb) 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 up to B-class (possibly up to C-class) intensity, mainly from AR2765. 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.
