SUNSPOT MONITORING – JUNE 29, 2020

979 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, June 29, 2020.

The sky was mostly clear but with intermittent moderate to fresh winds which provided good transparency but average to poor seeing at the time these images were taken.

The Sun remains generally inactive over the past 24 hours. The Sun returned to being spotless again after the recent departure from Earth-view of the developing small sunspot group AR2766 towards the southwestern limb. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. The Sun exhibited several huge eruptive prominence activities at the limbs (non-Earth-directed) and few stable mound filament at the far southern hemisphere 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.
