SUNSPOT MONITORING – JUNE 30, 2020

1024 944 alsadeemadmin

Here is today’s white-light solar image taken from Al Sadeem Observatory, June 30, 2020.

The sky was mostly covered with cirrus clouds with intermittent moderate winds which provided poor transparency and poor seeing at the time these images were taken.

The Sun remains generally spotless inactive over the past 24 hours, on its 2nd consecutive day. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. No H-alpha solar images were taken due to obstruction of clouds.

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.
