SUNSPOT MONITORING – FEBRUARY 27, 2020

No sunspot monitoring issued yesterday, February 26, 2020, due to unfavorable weather conditions (sandstorm) prevailed in daytime.

Here are today’s solar images taken from Al Sadeem Observatory, February 27, 2020.

The sky was partly cloudy with intermittent moderate to fresh winds which provided average to poor seeing and transparency at the time these images were taken.

Solar activity remains generally spotless and inactive today, extending its spotless day streak to 25 days. No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Not much going on with the Sun, only exhibiting short quiescent filaments at the northwestern and southeastern sections of the Sun’s disk, few moderately huge eruptive pillar and mound-shaped prominences at the northeastern limb, and a tiny enhanced plage along the western quadrant, 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.
