SUNSPOT MONITORING – DECEMBER 23, 2018

Here are today’s solar images taken from Al Sadeem Observatory, December 23  2018.

The sky was partly cloudy with intermittent light to moderate winds making the seeing and transparency good at the time these images were taken.

The Sun remains spotless as generally very low solar activity has persisted over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  H-alpha imagery showed few eruptive and quiescent prominences at the opposite (northwestern and southeastern) limbs and shallow filaments at the southern hemisphere.

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.
