SUNSPOT MONITORING – JULY 30, 2020

1002 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, July 30, 2020.

The sky was mostly clear with intermittent light to moderate breeze which provided good transparency and seeing at the time these images were taken.

Both visible unipolar sunspot groups AR2767 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha) and AR2768 (Axx/alpha) exhibited minimal to no changes in their respective sunspot structures and has remained stable and inactive with no significant flaring activity recorded over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 22. Few minor prominence activities with the exception of a huge eruptive one at the southeastern limb, alongside the tiny enhanced plages near AR2767 and AR2768, 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 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. For H-alpha imagery, the equipment used are Lunt 60mm H-alpha solar telescope, and QHYCCD290III mono camera; all mounted on Skywatcher EQ6 pro mount 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.
