SUNSPOT MONITORING – FEBRUARY 29, 2020

963 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, February 29, 2020.

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

Solar activity remains generally spotless and inactive today, extending its spotless day streak to 27 days. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0.  H-alpha imagery revealed some minor plasma ejection activities through the presence of small quiescent prominences at the northwestern and southwestern limbs, as well as an elongated filament at the far northwestern hemisphere as the only visible solar features.

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 QHYCCDIII mono 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.
