No solar images taken today, October 18, 2018, due to unfavorable sky condition (mostly cloudy) at the proposed time of observation.
Solar activity remains at very low levels over the past 24 hours. AR2725 has re-emerged after a day of disappearance, exhibiting a single tiny sunspot (Modified Zurich/Mcintosh sunspot classification: Axx/alpha) and was relatively inactive. No significant flaring activity associated with this active region was recorded by space weather agencies. The latest sunspot number (based on visual count and Wolf number calculation) is 11. H-alpha imagery reveals several huge eruptive prominences along opposite (northwestern and southeastern limbs), plages associated with AR2725 and small filaments across the disk.
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.
