SUNSPOT MONITORING – NOVEMBER 27, 2018

970 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, November 27, 2018.

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

The Sun is currently spotless, as AR2728 has decayed its spot structure in white-light imagery, but still visible as a plage in H-alpha imagery. No significant flaring activity associated to AR2728 was recorded over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  Other solar features captured were huge eruptive hedgerow prominences at the limbs and few tiny shallow filaments across the 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. 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.
