Here are today’s solar images taken from Al Sadeem Observatory, March 4, 2019.
The sky was clear with intermittent light to moderate winds which provided good transparency but average seeing at the time these images were taken.
The Sun remains in its generally spotless and inactive state as generally very low solar activity has persisted over the past 48 hours (from the previous monitoring). No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. A small area of pores were spotted in white-light imagery (encircled) being monitored for any progress. Tiny quiescent prominences with noticeable ejecting ones at the northeastern limb, and few small plages across the solar surface were 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 ZWO120MM CMOS 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.
