Here are today’s solar images taken from Al Sadeem Observatory, February 12, 2019.

The sky was partly cloudy with moderate to fresh breeze making the seeing and transparency poor at the time these images were taken.

The Sun remains on its spotless and relatively inactive state as generally quiet solar activity has persisted over the past 24 hours. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. In spite of absence of any sunspot regions, several plasma ejections in the form of prominences at the limbs; most prominent one is the huge eruptive prominence at the northwestern limb, and some small quiescent ones in other sections.

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.
