SUNSPOT MONITORING – MARCH 17, 2020

971 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, March 17, 2020.

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

The Sun remains in its spotless and generally inactive over the past 24 hours, extending its streak to 7 consecutive days (1 week). 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 few small quiescent prominences at the opposite (mostly at the northeastern and southwestern) limbs visible at the time 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.
