SUNSPOT MONITORING – NOVEMBER 28, 2017

Due to time and few equipment set-up constraints because of some important institution-related errands, only one full-disk visible solar image was taken this day, November 28, 2017.

The sky was clear with slight air turbulence making the seeing and transparency average at the time this image was taken.

Low-level solar activity has persisted over the past 24 hours. The lone visible sunspot group AR2689 continues to decay in structure gradually especially on its trailer spots. It is currently inactive and stable in magnetic configuration; produced a single weak B-class flare. The latest sunspot number (based on visual count and Wolf number calculation) is 14.

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 or C-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.
