SUNSPOT MONITORING – JUNE 14, 2019

1024 1016 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, June 14, 2019.

The sky was mostly clear (few thin cirrus clouds present) with light air turbulence which provided average seeing and transparency at the time these images were taken.

The Sun remains in its spotless and generally inactive state over the past 24 hours. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Several eruptive prominence activities mostly along the western limb were the only observable 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.
