SUNSPOT MONITORING – JUNE 24, 2019

Here are today’s solar images taken from Al Sadeem Observatory, June 24, 2019.

The sky was mostly clear with intermittent light to moderate winds which provided average seeing and transparency at the time these images were taken.

Solar activity has remained at very low levels over the past 24 hours. Two small areas of pores (currently undesignated) were spotted on the Sun’s disk which will be monitored for any significant development in the coming few days. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 2. H-alpha imagery revealed the small plages of these developing active regions, a stable filament at the far northern portion of the Sun’s disk and some tiny quiescent prominences at the limbs which are all minor and shall not cause any major geomagnetic effect in the next few days.

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.
