SUNSPOT MONITORING – OCTOBER 24, 2018

998 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, October 24, 2018.

The sky was mostly clear (some light cirrus clouds passing) with light air turbulence making the seeing and transparency good at the time these images were taken.

The Sun still exhibits no visible sunspot groups as generally very low solar activity prevailed throughout the day. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  H-alpha imagery revealed some huge eruptive prominences at the opposite (northwestern and southeastern) limbs and tiny plages across the Sun’s disk.

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 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.
