Here are today’s solar images taken from Al Sadeem Observatory, August 6, 2019.
The sky was mostly clear but with moderate northwesterly winds which provided good transparency but average seeing at the time these images were taken.
Newly designated tiny sunspot group AR2746 (Modified Zurich/Mcintosh sunspot configuration: Bxo/beta) has experienced gradual structure decay and was inactive over the past 24 hours. It is expected to remain inactive and continue on its disintegration, not posing any threat for major associated solar activity in the next few days. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 12. H-alpha imagery revealed few eruptive prominences at the limbs, as well as the associated plage of decaying AR2746.
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 ZWO120MM CMOS 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.
