Here are today’s solar images taken from Al Sadeem Observatory, June 25, 2019.

The sky was mostly cloudy with intermittent moderate winds which provided poor seeing and transparency at the time these images were taken.

Solar activity remained at very low levels over the past 24 hours despite the emergence of newly-designated sunspot groups AR2742 (barely seen) and AR2743 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha). Both are small, minor and gradually decaying in structure and are expected to remain so as it nears the western limb, reducing the chance of any significant flaring activity affecting Earth in the coming days.  The latest sunspot number (based on visual count and Wolf number calculation) is 22. H-alpha imagery revealed the associated small plages of the mentioned active regions as well as few quiescent tiny prominences at the limbs.

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 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.
