SUNSPOT MONITORING – JUNE 27, 2020

1017 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, June 27, 2020.

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

The Sun remains generally inactive over the past 24 hours. A small sunspot region (encircled; currently undesignated; barely seen in the white-light image due to average seeing) near the southwestern limb has recently emerged but found to be quiet and relatively stable. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. The Sun exhibited several prominence activities at the limbs (non-Earth-directed) as 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 and Lunt H-alpha solar telescope and QHYCCDIII mono 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.
