Here are today’s solar images taken from Al Sadeem Observatory, September 19, 2019.

The sky was clear with light air turbulence making the seeing and transparency good 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. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  Few minor plasma ejections through the presence of quiescent prominences at the limbs (including an eruptive one at the southeastern limb) and shallow filaments across the Sun’s disk were the only visible solar features at the moment 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.
