SUNSPOT MONITORING – MAY 9, 2020

1009 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, May 9, 2020.

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

The Sun remained spotless and inactive over the past 24 hours, extending to its 7th consecutive day. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Not much changes occurred with the Sun lately except for few moderately huge prominences at the opposite (northeastern and southwestern) limbs and some few short stable filaments at the far southern hemisphere, 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.
