Here are today’s solar images taken from Al Sadeem Observatory, January 24, 2019.

The sky was clear with light air turbulence making the seeing and transparency good at the time these images were taken.

The lone visible sunspot group AR2733 (Modified Zurich/Mcintosh sunspot configuration: Dro/beta) has expanded in coverage area but shown signs of gradual structure decay. However, it was generally quiet; did not produce any significant flaring activity throughout the monitoring period. The latest sunspot number (based on visual count and Wolf number calculation) is 18.  H-alpha imagery revealed clear plage structure of AR2733, a long stable filament at the far southern hemisphere, and several huge eruptive prominences at the limbs, including the ejected one at the northwestern limb.

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 (possibly up to isolated C-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 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.
