SUNSPOT MONITORING – APRIL 23, 2018

No sunspot monitoring information was issued yesterday, April 23, 2018, due to unfavorable weather condition (mostly cloudy) at the proposed time of observation.

The lone visible sunspot group AR2706, though continuously gradually growing in structure, has been quiet and did not produce any significant flaring activity as solar activity remains relatively very low over the past 24 hours.  The latest sunspot number (based on visual count and Wolf number calculation) is 18. Few eruptive prominences at the western limb and tiny plages (most distinctive at AR2706) across the Sun’s visible disk were clearly seen in H-alpha imagery.

Space weather agencies* forecast solar activity to remain relatively low with chances of continuity of isolated B-class (possibly up to C-class) solar flaring activity mainly from AR2706. 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.

SUNSPOT MONITORING – APRIL 22, 2018

No solar images were taken today, April 22, 2018, due to important institution-related errands being done by the observer at the proposed time of observation.

Over the past 24-hour monitoring period, AR2706 sightly grew in structure but produced fewer and weaker B-class flares than previous. Another small active region designated AR2707 emerged few degrees southeast of AR2706, yet decayed shortly.  Few tiny plages and prominences were distinctively seen in H-alpha imagery.

SUNSPOT MONITORING – APRIL 17, 2018

No solar images were taken today, April 17, 2018, due to unfavorable condition (thunderstorm) at the proposed time of observation.

Solar activity remains at very low levels over the past 24 hours. During the past 24 hours, space weather agencies designated the area of pores observed in the central region of the Sun’s visible disk as AR2705 (refer to the previous post) but decayed shortly. read more
