SUNSPOT MONITORING – JANUARY 14, 2019

992 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, January 14, 2019.

The sky was partly cloudy with intermittent light to moderate breeze making the seeing and transparency average to poor at the time these images were taken.

The Sun remains spotless as generally quiet solar activity has persisted over the past 24 hours. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  Not much solar features visible except for few small quiescent prominences at the limbs 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 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.
