Sun – AR1726
A beautiful morning with clear blue skies and our sun gaining in altitude this springtime. Although the sun is reaching its solar maximum, today’s activity was not that high. However, active region AR1726 was interesting to watch through the Ha spectral line. Some smaller solar flares were visible as well.
