SUNSPOT MONITORING – MAY 13, 2018

1024 1024 alsadeemadmin

No solar images were taken issued today, May 13, 2018, due to unfavorable weather condition (dust storm) at the proposed time of observation.

 

Solar activity remains at very low levels over the past 24 hours. Some tiny pores were seen popping out in the lone visible sunspot group AR2709, otherwise, its sunspot structure has unchanged. The latest sunspot number (based on visual count and Wolf number calculation) is 12.  Few prominences at the western limb, plages associated with AR2709 and former active regions, and filaments across the Sun’s disk were observed 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.
