(6) 특정 유성의 경우 경로는 모든 나침반 방향으로 동일한 빈도로 향합니다. 반대로 녹색 화구의 경우, 허용 가능한 접근 구역의 도표는 경로가 하늘의 북쪽 절반에서 들어오는 매우 뚜렷한 경향이 있음을 보여줍니다.
(6) In the case of certain meteors the paths are directed to- ward all points of the compass with equal frequency. On the contrary in the case of the green fireballs, plots of admissible approach sec- tors show that there is a very pronounced tendency for the paths to come in from the north half of the sky.

(7) 세 그룹의 비정상적인 녹색 발광 현상은 잘 알려진 유성우와 기묘한 연관성을 보입니다. 비록 이러한 유성우 중 어느 것도 최근 관측된 것과 같은 극도로 밝은 녹색 화구를 일반적으로 생성하지는 않지만 말입니다. 예를 들어, 관측-
(7) The three groups of anomalous greenish luminous phenomena show a curious association with well known meteor showers, although none of these meteor showers normally produce extremely bright green fireballs, such as those recently observed. For example, the obser-

관측은 모두 쌍둥이자리 유성우 기간에 해당했습니다. 이러한 관계는 상당한 유성 활동이 있을 때만 나타나게 하여 녹색 화구를 덜 눈에 띄게 만들려는 시도를 나타낼 수 있습니다.
observations all fell in the interval covered by the Geminid shower. This relationship might indicate an attempt to render the green fire- balls less conspicuous by causing them to appear only when there is considerable meteoric activity.

(8) 이전 통신에서 언급했듯이, 대부분의 12월 화구에서 보고된 놀랍도록 선명한 녹색은 실제 유성에서는 거의 관측되지 않습니다. 실험실 테스트에 따르면 이 특이한 색상은 불꽃에 구리 염을 넣었을 때 방출되는 색상과 동일한 것으로 보입니다. 이 식별이 정확하다면, 녹색 화구에서 나오는 복사선의 파장은 λ -5210Å 근처입니다.
(8) As noted in an earlier communication, the remarkably vivid green color reported for most of the December fireballs is rarely observed in the case of genuine meteors. By laboratory test this peculiar color seems to be identical with that given off by copper salts in the blowing flame. If this identification is correct, the wave length of the radiation from the green fireballs is near λ -5210Å.

(9) 녹색 화구에 대해 보고된 2~3초 사이의 지속 시간 추정치는 일반적인 시각 유성(0.1~0.5초)보다 상당히 길지만, 실제 운석 낙하(5~30초 또는 그 이상)의 경우 항상 보고되는 지속 시간 추정치보다는 짧습니다.
(9) The duration estimates of between 2 and 3 seconds reported for the green fireballs are considerably longer than those (0.1 - 0.5 seconds) for the ordinary visual meteors, but shorter than the duration estimates invariably reported in the case of a genuine meteorite fall (5 to 30 seconds or even longer).

(10) 녹색 화구 중 어느 것도 불꽃의 흔적이나 먼지 구름이 보고된 바 없습니다. 이는 유성 화구의 경우, 특히 12월 12일의 녹색 화구가 관측된 매우 낮은 고도까지 침투하는 유성 화구의 경우에 관찰된 행동과 극명한 대조를 이룹니다.
(10) For none of the green fireballs has a train of sparks or a dust cloud been reported. This contrasts sharply with the be- havior noted in case of meteoric fireballs--particularly these that penetrate to the very low levels where the green fireball of December 12 was observed.

2. 이 목록이 작성된 지 1년 반 동안 많은 추가 관측이 이루어졌으며, 현재 녹색 화구 범주에 보고된 총 물체 수는 72개입니다. (이 숫자는 첨부된 요약에 나열된 화구의 거의 5%를 구성하지만, 필자에게 보고된 미검토 관측 총수의 5% 미만을 구성합니다.) 현재 이용 가능한 모든 녹색 화구 보고서에 대한 비판적 분석은 1항에 제시된 목록의 진술 중 하나만 수정할 필요가 있음을 보여줍니다. 즉, 항목 (1)입니다. 지난 1년 동안 상당수의 녹색 화구가 수직으로 아래로 떨어지는 것처럼 보였습니다.
2. In the year and a half since this list was prepared, many ad- ditional observations have been made, the total number of objects now reported in keeping in the green fireball catagory being 72. (Al- though this number constitutes nearly 5% of the fireballs listed in the accompanying Summary, it constitutes less than 5% of the total number of unscreened observations reported to the writer.) Critical analysis of all green fireball reports now available shows that only one of the statements in the list given in paragraph 1 needs to be modified, namely, item (1). Within the last year, a considerable number of the green fireballs have appeared to fall vertically downward rather than
