Here are today’s solar images taken from Al Sadeem Observatory, June 26, 2019.

The sky was mostly clear with slight haze and moderate winds which provided average to poor seeing and transparency at the time these images were taken.

The sunspot regions from yesterday AR2742 (disintegrated) and AR2743 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha) have experienced significant structure decay as generally quiet solar activity has persisted over the past 24 hours. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 11. H-alpha imagery revealed the remnant plage of the decaying AR2743, as well as several quiescent prominences at the limbs.

With this stance regarding the decay and departure of these minor sunspot groups, 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. 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.
