Here are today’s solar images taken from Al Sadeem Observatory, October 2, 2019.
The sky was clear with moderate to fresh breeze which provided good transparency but average seeing at the time these images were taken.
Generally very low solar activity has persisted over the past 24 hours. The newly designated AR2749 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha) was found quiet and decaying gradually throughout the monitoring period. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 11. H-alpha imagery revealed some huge eruptive prominences at the limbs, together with the associated small plage of AR2749.
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 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.
