SUNSPOT MONITORING – FEBRUARY 24, 2020

601 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, February 24, 2020.

The sky was partly cloudy with intermittent light winds which provided good seeing but average to poor transparency at the time these images were taken.

Solar activity remains generally spotless and inactive today, extending its spotless day streak to 22 days. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. The Sun exhibited a couple of short quiescent prominences at the far northern hemisphere and a huge eruptive prominence at the northeastern limb, as distinctively captured in H-alpha imagery.

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.
