SUNSPOT MONITORING – DECEMBER 28, 2018

Here are today’s solar images taken from Al Sadeem Observatory, December 28, 2018.

The sky was partly to mostly covered with high cirrus clouds and light to moderate winds making the seeing and transparency average to poor at the time these images were taken.

The Sun remains spotless and relatively inactive with no significant flaring activity recorded as generally very low solar activity has persisted over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  Several eruptive prominences at the limbs and the remnant plage of the former AR2729 were still visible in the Sun’s disk 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.
