SUNSPOT MONITORING – MARCH 2, 2021

Here are today’s solar images taken from Al Sadeem Observatory, March 2, 2021.

The sky was mostly clear with intermittent light breeze which provided good transparency and seeing at the time these images were taken. 

Two new enhanced regions were seen developing at the Sun’s southern hemisphere (encircled) which are both undesignated throughout the monitoring period due to some structural decay.  Once both developing sunspot groups sustain their respective structures, it shall be designated as AR2806 and AR2807 respectively by space weather agencies. No significant flaring activity was recorded over the past 24 hours. The latest sunspot number (based on visual count and Wolf number calculation) is 6.

Other noteworthy solar features observed were some shallow elongated eruptive prominences at the extreme northeastern and southwestern limbs, as well as the enhanced plages associated with the developing sunspor groups, as distinctively captured in H-alpha imagery.

Space weather agencies* forecast solar activity to be at low levels with chances of solar flares of 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. For H-alpha imagery, the equipment used are Lunt 60mm H-alpha solar telescope, and QHYCCD 290III mono camera; all mounted on Skywatcher EQ6 pro mount 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.
