The sky was mostly cloudy with intermittent light to moderate winds which provided poor seeing and transparency at the time these images were taken (imaged through a brief sky window). Here are today’s solar images taken from Al Sadeem Observatory, April 29, 2019.
Solar activity remains at very low levels over the past 24 hours. No active sunspot regions currently exist on the Sun’s visible disk. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0.
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. 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 and Lunt H-alpha solar telescope, 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.
