Here are today’s solar images taken from Al Sadeem Observatory, November 4, 2019.
The sky was clear with intermittent moderate breeze which provided good transparency but average seeing at the time these images were taken.
Solar activity remains at very low levels over the past 24 hours. Both inactive sunspot regions, AR2750, and AR2751 (designated yesterday, November 3, 2019), have decayed completely in structure. No significant flaring activity was recorded. Meanwhile, two small pores were spotted to have recently emerged at the encircled region which will be closely monitoring its development within the next 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 2. The small enhanced plages of the decayed sunspot regions and the developing one, together with few tiny quiescent prominences were 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. 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.
