SUNSPOT MONITORING – JULY 30, 2018

No solar images were taken today, July 30, 2018, due to unfavorable (dusty) weather condition at the proposed time of observation.

Solar activity remains at very low levels over the past 24 hours. Despite the absence of any sunspots, space weather agencies recorded a weak B-class solar flare courtesy of the undesignated active (faculae) region which has rotated from the eastern limb. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  Several huge eruptive prominences at the limbs, few tiny filaments and the associated plage of the recently appeared unnumbered active region 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, primarily from the upper-mentioned 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.
