Here are today’s solar images taken from Al Sadeem Observatory, February 10, 2020.
The sky was partly cloudy with intermittent light to moderate winds which provided average transparency and seeing at the time these images were taken.
Solar activity remains at very low levels over the past 24 hours. No sunspot groups were visible at this moment. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Not much going on with the Sun lately except for a couple of minor small to moderately huge quiescent prominences and short filaments mostly along the western section of the Sun’s disk as distinctively captured 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. 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 and QHYCCDIII mono camera for H-alpha 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.
