Mostly cloudy sky condition prevailed throughout the day. Here is today’s visible solar imagery taken from Al Sadeem Observatory, November 16, 2018.
AR2726 has completely disintegrated and vanished. The newly-emerged sunspot group seen yesterday was designated as AR2727. Over the past 24 hours, it showed some signs of gradual sunspot structure decay. No significant flaring activity associated with AR2727 was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 14.
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.
Equipment used are Skywatcher 120mm refractor telescope with Baader filter and unmodified Canon EOS 1D Mark IV DSLR camera for visible imagery, mounted on Skywatcher EQ6 Pro. Pre-processing of visible solar images was performed in PIPP, stacking in Autostakkert, slight wavelet adjustments in Registax 6 and post-processing in Adobe Photoshop CC.
