Here are today’s solar images taken from Al Sadeem Observatory, April 18, 2018.
The sky was clear but experienced intermittent light to moderate winds making the seeing and transparency good to average at the time these images were taken.
Solar activity remains at very low levels over the past 24 hours. No active sunspot regions currently exist on the Sun’s visible disk. The yesterday’s tiny pore spotted did not develop and decayed eventually. However, another single small spot was seen at the near-central portion of the Sun’s visible disk (encircled). This will be monitored closely for any significant development in the next couple of hours. The latest sunspot number (based on visual count and Wolf number calculation) is 1. Some plages and prominences were distinctively captured 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.
