Here are today’s solar images taken from Al Sadeem Observatory, January 7, 2020.
The sky was clear with intermittent light to moderate winds which provided good transparency but average seeing at the time these images were taken.
AR2755 has decayed its spot structure into plage. Meanwhile, a new developing active region was spotted to have turned into Earth-view from the eastern limb. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 1. H-alpha imagery captured some small quiescent prominences at the limbs and plages associated with the small active regions with few short eruptive filaments near the decaying AR2755.
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.
