SUNSPOT MONITORING – DECEMBER 1, 2018

1007 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, December 1, 2018.

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

Generally very low solar activity has persisted over the past 24 hours. The Sun remains spotless without any significant flaring activity over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  Not much solar features were visible aside from several eruptive and quiescent prominences at the limbs as seen 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.

    Hello people from the Al Sadeem.I would like to congratulate you for the persistent and professional sunspot monitoring. I am now able to follow your posts through a small Coronado PST, from my balcony. I`ve been following the sun activity (of course not with such quality and professionalism as you) since long and if I a recall correctly, since around 2012 we are into a low. Is it not time already for an increase in the sun`s activity?
    Best regards,

    Weber Barbosa
