SUNSPOT MONITORING – APRIL 30, 2018

Partly cloudy sky condition with light to moderate breeze was experienced during the observation period.

Here is the monochrome visible solar imagery taken from Al Sadeem Observatory, April 30, 2018. No H-alpha image was captured because of the presence of too many clouds where the Sun the situated in the sky at that time.

Solar activity remains at very low levels in which the Sun is currently spotless. No significant flaring activity was recorded over the past 24 hours.  The latest sunspot number (based on visual count and Wolf number calculation) is 0. The plage from former AR2706 was seen approaching the Sun’s western limb as depicted in the visible imagery while some small filaments across the Sun’s southern hemisphere and loop prominences at the eastern limb were distinctively seen 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.
