Here are today’s solar images taken from Al Sadeem Observatory, June 22, 2019.
The sky was slightly hazy with high cirrus clouds covered much of the sky and moderate winds prevailed which provided poor seeing and transparency at the time these images were taken.
Solar activity was generally dormant over the past 24 hours. No active sunspot regions currently exist on the Sun’s visible disk. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Most of the plasma ejection activity has subsided as filaments from yesterday have receded back into the solar surface (appearing short and faint across the Sun’s disk) and some tiny quiescent prominences at the limb were the only solar features observed 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 ranging 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 ZWO120MM CMOS 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.
