Here are today’s solar images taken from Al Sadeem Observatory, November 13, 2018.

The sky was partly cloudy with intermittent light to moderate (to at times fresh) winds making the seeing and transparency average to poor at the time these images were taken.

The lone visible sunspot group AR2726 experienced a slight growth in its leader spot, but was relatively quiet, absent of any recorded significant flaring activity associated to it. The latest sunspot number (based on visual count and Wolf number calculation) is 13.  Some huge eruptive hedgerow prominences, and the plage associated with AR2726 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. 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.
