Here are today’s solar images taken from Al Sadeem Observatory, May 29, 2019.
The sky was mostly clear with little air turbulence which provided excellent seeing and transparency at the time these images were taken.
Solar activity remains at very low levels over the past 24 hours. No active sunspot regions currently exist on the Sun’s visible disk. The latest sunspot number (based on visual count and Wolf number calculation) is 0. H-alpha imagery revealed few plasma ejections, including a huge eruptive prominence at the north-northeastern limb (expected to rotate further towards Earth-view becoming a filament in the next days) and a tiny plage at the near-central portion of the Sun’s disk.
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.
