Here are today’s solar images taken from Al Sadeem Observatory, June 15, 2020.
The sky was mostly covered with cirrus clouds with intermittent moderate winds which provided average to poor transparency and seeing at the time these images were taken.
The lone visible sunspot group AR2765 has recently approached the southwestern limb, rotated out of Earth-view, leaving the Sun currently spotless. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Some moderately huge quiescent prominences at the limbs were the only visible solar features as 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 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.
