SUNSPOT MONITORING – MAY 25, 2018

Due to unfavorable weather condition (overcast sky) at the proposed time of observation, no solar images were taken from the observatory.

As of posting time, there are two sunspot groups currently visible in the Sun’s disk. AR2711 and the newly designated AR2712 further developed in magnetic complexity but currently dormant of flaring activity over the past 24 hours. On the other hand, AR2710 produced a B9.8 class flare, according to space weather agency records before it recently lost its sunspot structure. The latest sunspot number (based on visual count and Wolf number calculation) is 40. H-alpha imagery reveals associated plages of the visible active regions and few tiny prominences, mostly in the Sun’s southern hemisphere.

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.
