SUNSPOT MONITORING – JULY 7, 2020

SUNSPOT MONITORING – JULY 7, 2020

990 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, July 7, 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.

AR2766 has decayed completely over the past 24 hours. Meanwhile, a new small bipolar sunspot region (with reversed magnetic polarity; belonging to Solar Cycle 25) was seen emerging at the encircled location. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 2. The Sun also exhibited some plasma ejection activities through the presence of few moderately huge prominences at the northeastern limb and small plages associated with the new emerging sunspot region and former AR2766 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.
