2017年11月・12月用

今回より2017/18年の火星観測の為の物理暦表の掲載を始める。はじめには
1 November 2017から31 December 2017までの二ヶ月を載せる。今後の号で引き続き連載の予定である。データは00:00
GMT (TDTではない)の値を採用する。記号ω、φはそれぞれ中央子午線の経度と中央緯度を意味する。更に、われわれはλ、δ、ιという記号を使うが、それぞれLsで測った季節、視直径、位相角(位相ではない)を示す。他にΠという欄があるが、これは北点から東向きに測ったときの火星の軸の傾きを示す。これはp←(赤道儀を止めたときの火星の動く方向)によって極の方向を探し出すのに有用である。最後に視赤緯(D )を示す。火星が薄明時など微弱にしか見えないとき、赤道儀の場合この値によって容易に火星を見つけ出すことが出来る。全データは米英暦 The Astronomical Almanac
for the Year 2017 に依った。
