SUNSPOT MONITORING – DECEMBER 5, 2018

1019 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, December 5, 2018.

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

A new sunspot group has emerged and was designated as AR2729 (Modified Zurich/Mcintosh sunspot configuration: Bro/beta) configuration. Upon its emergence and rapid growth, it produced minor weak B-class solar flares. Currently possessing bipolar  The latest sunspot number (based on visual count and Wolf number calculation) is 19.  Other solar features were few small quiescent prominences which were 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, mainly from AR2729. 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.

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.
