SUNSPOT MONITORING – JULY 28, 2018

No solar images were taken today, July 28, 2018, due to unfavorable weather condition (dusty sky) at the proposed time of observation.

Very low solar activity has persisted over the past 24 hours. The Sun currently exhibits no visible active regions and few weak A-class flares were recorded from a possible active region at the backside approaching the eastern limb. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  Several tiny prominences at the limbs and the huge filaments approaching the northwestern limb were 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 solar flares ranging up to B-class (possibly isolated C-class) intensity. Close monitoring is being conducted by numerous space weather agencies for any significant development.
