SUNSPOT MONITORING – JULY 11, 2018

Due to passing high cirrus clouds and slightly hazy sky condition with moderate winds, only the visible-light image of the Sun was taken from Al Sadeem Observatory, for today’s sunspot monitoring, July 11, 2018. Attached below is false-color H-alpha imagery courtesy of daystarfilters.com.

The recurrent active region (appearing as a region of plages) still exhibits inactivity with no significant flaring activity recorded over the past 24 hours.  The latest sunspot number (based on visual count and Wolf number calculation) is 0. Several tiny prominences (which are receding plasma ejections) at the limbs and the upper-mentioned plage were also seen in H-alpha imagery.

Space weather agencies* forecast solar activity to remain at low with chances of isolated B-class to possibly C-class solar flares, mainly from the unnumbered active region. 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.
