A New Sunspot!

새로운 흑점 출현!

33일만에 나타난 흑점입니다. 지난 2월 한달 동안 흑점이 없었던 경우는 2008년 이후 처음이었습니다.

앞으로 2주 정도 관측이 가능할 것 같습니다.

태양 홍염과 비행기.

스마트 폰으로 태양 홍염을 촬영하고 있는데 폰 화면에서 갑자기 비행기가 보이길래 급하게 바로 찍었는데 운이 좋게도 2장에 걸렸네요. ^^ 

아무래도 망원경 접안렌즈에 핸드폰을 손으로 들고 찍다보니 촬영이 쉽지 않았는데 행운이 따른 것 같습니다.  두 사진을 2초 안에 찍었네요.

갤럭시 노트 8 프로 모드로 찍었습니다.

촬영 장소: 전북 익산시 전라북도과학교육원 주관측실.

The return of the large sunspot (called AR2673).  

거대 흑점의 귀환.

For the past two weeks, AR2673 has been transiting the backside of the sun, carried around by the sun's 27-day rotation.
