質問: 去年、スターリンク衛星で「電車に乗り遅れた」のですが、今ではそれがseparatedであるように見え、保守的な声がスペースXにバイザーやペイントで新しいものを暗くするよう説得しました。 2つ以上の衛星が肉眼で同じ方向に動いているのをまだ確認できますか?(実際には、同じ方向に目に見える形で移動している天体はすべて実行されます。) 私はカリフォルニアに住んでいて、Find StarlinkとHeavens Aboveアプリを試しましたが、何も表示されませんでした。
回答: I can personally attest that the Starlink satellites are visible with the naked eye even after they have spread out, however they are quite dim - with apparent magnitudes near 5.5. Here is a brightness comparison drawn from a widefield capture where two Starlink satellites are can be seen (albeit barely) juxtaposed with another satellite with apparent magnitude near 3. !enter image description here The region in which this was taken is Class 1 on the Bortle Scale and the entire 60-satellite train was visible, though only 4-5 were visible at any given time. In brighter regions the satellites would not be as readily visible. Furthermore, since they have such low orbits, they were only visible for ~105 degrees in the sky before they passed into Earth's shadow.
