SUNSPOT MONITORING – MARCH 25, 2020

1024 999 alsadeemadmin

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

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

The Sun remains in its spotless and generally inactive state over the past 24 hours, extending its streak to 15 consecutive days. No major flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Not much significant going on with the Sun lately except for several huge eruptive prominences at the limbs and a tiny disintegrating (spotless) enhanced plage at the northeastern quadrant as the only visible solar features 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.
