SUNSPOT MONITORING – JANUARY 13, 2019

Here is today’s white-light solar imagery taken from Al Sadeem Observatory, January 13, 2019.

The sky was partly to mostly cloudy with light air turbulence which provided good seeing but poor transparency. No H-alpha imagery was captured as the clouds rolled in.

Solar activity remains at very low levels over the past 24 hours. No active sunspot regions currently exist on the Sun’s visible disk. 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. 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.
