SUNSPOT MONITORING – OCTOBER 15, 2018

Here is the monochrome visible solar imagery taken, October 15, 2018 taken from Al Sadeem Observatory. 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.

The sky was mostly cloudy with intermittent light to moderate air turbulence providing average to poor seeing and transparency at the time these images were taken.

The two visible sunspot groups AR2724 and AR2725 (Modified Zurich/Mcintosh sunspot/magnetic classification: Axx/alpha) both exhibit single sunspot structure and were inactive. No significant flaring activity associated with these two active regions was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 22.

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. The extent of the frequency and intensity of the Sun’s activity will highly depend on the magnetic flux fluctuations happening in the visible ARs in the coming days. Close monitoring is being conducted by numerous space weather agencies for any significant development.
