✦ Synopsis

Though the times of these disturbances did not show the expected relation with the central meridian passage of the sunspots, the region of the return sunspot group was the most likely source of disturbance visible on the sun.

Summarizing, severe radio and other terrestrial effects were very pronounced during the original passage of the sunspot group in February, and were less pronounced during its return in March.
