SUNSPOT MONITORING – APRIL 25, 2020

Here are today’s solar images taken from Al Sadeem Observatory, April 25, 2020.

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

A small pore/sunspot was spotted emerging on the enhanced plage region at the east-southeastern section of the Sun’s disk (currently undesignated). The latest sunspot number (based on visual count and Wolf number calculation) is 11. Not much significant going on with the Sun lately aside from a shallow elongated filament near the northeastern limb which seems to fall back into the Sun’s surface as distinctively captured in Halpha imagery.

Space weather agencies* forecast solar activity to remain at 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.
