SUNSPOT MONITORING – MAY 27, 2018

Here are today’s solar images taken from Al Sadeem Observatory, May 27, 2018.

The sky was partly cloudy with intermittent light to moderate breeze making the seeing and transparency average to poor at the time these images were taken.

AR2712 experienced gradual decay in the leader spot portion but produced several weak B-class flares over the past 24 hours, based on space weather agency records. AR2711’s sunspot structure has not changed much and was inactive as it approaches the western limb. The latest sunspot number (based on visual count and Wolf number calculation) is 27.  Few tiny prominences at the limbs, as well as associated plages from the two visible sunspot groups, were distinctively captured in H-alpha imagery.

With this stance, space weather agencies forecast a slight drop in solar activity in the next few days as AR2711 departs from Earth-view in the next couple of hours; ranging only from few B-class to isolated C-class solar flares, mainly from these two visible active regions. 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.
