SUNSPOT MONITORING – NOVEMBER 10, 2018

1024 1013 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, November 10, 2018.

The sky was mostly clear but experienced moderate to fresh winds making the seeing and transparency average at the time these images were taken.

The lone visible sunspot group SIDC Catania group 1 (encircled) shrunk a bit in structure, otherwise unchanged, and was relatively inactive; produced few weak A-class flares based on space weather agency records.  The latest sunspot number (based on visual count and Wolf number calculation) is 1.  H-alpha imagery reveals few eruptive and quiescent prominences at the opposite (northeastern and southwestern) limbs, the tiny plage associated with SIDC Catania group 1, and an expelling filament at the Sun’s northern 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. 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.
