SUNSPOT MONITORING – JULY 11, 2020

970 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, July 11, 2020.

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

Over the past 24 hours, space weather agencies confirmed that the tiny spots emerged yesterday come from the former AR2766 which is approaching the western limb, but it is found to be gradually disintegrating in the process. However, due to the relatively average to poor seeing conditions, it is barely seen in white-light solar imagery. Other than that, the Sun remains generally inactive over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 0. No significant flaring activity was recorded. Nothing much going on significantly with the Sun lately except for some tiny quiescent prominences at the opposite (northeastern and southwestern) limbs 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. 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.
