SUNSPOT MONITORING – MARCH 19, 2018

No solar images were taken today, March 19, 2018, due to some important institution-related errands at the proposed time of observation.

 

Solar activity remains at very low levels over the past 24 hours.Very low solar activity has persisted over the past 24 hours. The lone visible sunspot group AR2702 has decayed slightly in structure as it remained inactive with no significant flaring activity associated with it recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 13.  Few tiny filaments across the disk and prominences at the limbs were distinctively 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. 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.
