SUNSPOT MONITORING – DECEMBER 14, 2018

1021 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, December 14, 2018.

The sky was clear with light air turbulence 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. A potential forming active region was seen emerging at the mid-eastern part of the Sun’s disk. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  A huge eruptive prominence at the northwestern limb, and few small quiescent ones, as well as small plages associated with former AR2730 and the potential forming active region were 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.
