No sunspot monitoring information was issued yesterday, May 22, 2019, due to unfavorable weather condition at the proposed time of observation.

Here are today’s solar images taken from Al Sadeem Observatory, May 23, 2019.

The sky was mostly cloudy (imaged through brief sky windows) with intermittent light to moderate winds which provided average to poor seeing and transparency at the time these images were taken.

The Sun remains in its spotless and generally inactive state over the past 2 days. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  Not much solar features were visible except for a few tiny prominences at the limbs.

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. 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.
