SUNSPOT MONITORING – MARCH 15, 2019

1024 944 alsadeemadmin

Mostly cloudy skies (imaged through a brief sky window) with moderate to strong winds which provided poor seeing and transparency. Here is today’s white-light solar image taken from Al Sadeem Observatory, March 15, 2019.

The Sun remains in its spotless and inactive state as generally very low solar activity has persisted over the past 24 hours. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Not much solar features visible at the moment except for a scattered plage region at the eastern limb.

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, 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.
