SUNSPOT MONITORING – MARCH 10, 2020

1013 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, March 10, 2020.

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

AR2758 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha) has significantly decayed in structure (almost barely seen) over the past 24 hours and was generally inactive. The latest sunspot number (based on visual count and Wolf number calculation) is 11.  A couple of huge eruptive prominences at the northwestern and southwestern limbs(all non-Earth directed), as well as the associated elongated enhanced plage of AR2758, were 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, mainly from AR2758. 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.
