SUNSPOT MONITORING – JULY 29, 2019

Here is today’s white-light solar image taken from Al Sadeem Observatory, July 29, 2019.

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

The Sun remains spotless as generally very low solar activity has persisted over the past 48 hours. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0.

Space weather agencies* forecast solar activity to remain at very low levels with chances of weak X-ray fluxes or flares ranging 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 ZWO120MM CMOS 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.
