Here are today’s solar images taken from Al Sadeem Observatory, December 10, 2018.
The sky was clear with intermittent light to moderate winds making the seeing and transparency average at the time these images were taken.
With the recent departure of AR2729 (produced some minor B-class flares) from Earth-view, the Sun is currently spotless as generally very low solar activity prevails over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 0. H-alpha imagery captured several huge eruptive prominences at the limbs, including the one associated with the recently departed AR2729 at the western limb.
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.
