SUNSPOT MONITORING – NOVEMBER 2, 2019

995 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, November 2, 2019.

The sky was clear with moderate to fresh breeze which provided good transparency but average to poor seeing at the time these images were taken.

Solar activity remains at very low levels over the past 24 hours. The newly designated AR2750 (Modifed Zurich/Mcintosh sunspot configuration: Axx/alpha) situated at the far southern hemisphere (barely seen in white-light imagery due to poor seeing) has been gradually decaying in structure and generally inactive throughout the monitoring period. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 11. Another small enhanced plage was observed at the near-central portion of the Sun’s disk, together with few moderately huge eruptive 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.
