SUNSPOT MONITORING – AUGUST 7, 2019

1024 759 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, August 7, 2019.

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

Over the past 24 hours, space weather agencies monitored the short emergence of newly designated AR2747 (Modified Zurich/Mcintosh sunspot configuration: Axx/alpha) situated near the central region of the Sun’s disk and decayed shortly (barely visible in white-light imagery and appearing as a small magnetically stable plage in H-alpha imagery). No significant flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 11.  Not much solar features were visible, signifying overall solar inactivity throughout the monitoring period.

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.
