March is the best month of the year for auroras 3월이 오로라 관측에 가장 좋은 달 Did you know that March is the best month of the year for auroras? It's true. A 75-year study shows that March has more geomagnetically active days than any other month of the year. 3월이 오로라 관측에 가장 좋은 달이라는 사실을 알고 있나요? 사실입니다. 75년간의 연구에 따르면 3월은 일년 중 다른 어느 달보다 지자기 활동이 더 많은 날이 있는 것으로 나타났습니다. cf. 오로라 관측은 3월, 4월, 9월, 10월이 좋은 시기이며, 3월과 10월이 더 좋은 시기인 것같습니다.
