SUNSPOT MONITORING – OCTOBER 12, 2018

Here are today’s solar images taken from Al Sadeem Observatory, October 12, 2018.

The sky was clear with light air turbulence making the seeing and transparency good at the time these images were taken.

A new bipolar sunspot group has emerged at the eastern section of the Sun’s disk and was designated as AR2724 (Modified Zurich/McIntosh sunspot classification: Bxo/beta). It produced a weak B-class solar flare based on space weather agency records. The latest sunspot number (based on visual count and Wolf number calculation) is 12.  H-alpha imagery reveals few eruptive prominences mostly from the western section of the Sun’s disk, some fairly large filaments across the disk and plages associated with AR2724.

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 for H-alpha imagery, mounted on Skywatcher EQ6 Pro. Pre-processing of visible solar images was performed in PIPP, stacking in Autostakkert3, slight wavelet adjustments in Registax 6 and post-processing in Adobe Photoshop CC.
