SUNSPOT MONITORING – MAY 26, 2018

No solar images were taken today, May 26, 2018, from the observatory due to unfavorable weather condition (overcast) at the proposed time of observation.

An isolated weak B-class solar flares originated from AR2711 was recorded by space weather agencies. A slight structure decay was observed at its intermediate and trailer spots. On the hand, AR2712 was dormant of any flaring activity and exhibit very little change in leader sunspot structure. The latest sunspot number (based on visual count and Wolf number calculation) is 34.  Several plages associated with the two mentioned sunspot groups and the former AR2710, as well as few tiny prominences at the southeastern limb were distinctively seen in H-alpha imagery.

Space weather agencies* forecast chances of minor solar flares ranging from B-class to isolated C-class flares mainly from AR2711 and AR2712 as the solar activity will remain at relatively low levels. 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.
