Here are today’s solar images taken from Al Sadeem Observatory, November 20, 2018.

The sky was mostly clear with intermittent light to moderate winds making the seeing and transparency average at the time these images were taken.

The lone visible sunspot group AR2727 (Modifed Zurich/Mcintosh sunspot classification: Axx/alpha) has decayed further in structure as it is about to depart from Earth-view at the western limb. The sunspot region was generally inactive and did not produce any significant activity. The latest sunspot number (based on visual count and Wolf number calculation) is 11.  H-alpha imagery reveals some eruptive prominences, including a pyramid and mound-shaped ones at the eastern limb, as well as the associated plage of AR2727.

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. The extent of the frequency and intensity of the Sun’s activity will highly depend on the magnetic flux fluctuations happening in the visible ARs in the coming days. 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 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.
