Here are today’s solar images taken from Al Sadeem Observatory, June 27, 2019.

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

Over the past 24 hours, the Sun has left spotless with the recent disintegration of AR2743 as it also about to depart from Earth-view towards the western limb. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. The tiny remnant plages of AR2743 near the western limb and another scattered one which recently rotated into Earth-view from the eastern limb, as well as some huge eruptive prominences mostly along the eastern limb,  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 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.
