長い昼間の時間・・・・一日を有効に過ごしたい

　

　今日６月１７日の日の出は４時２５分【群馬県】、日の入は１９時０４分です。このため今日の昼の時間は１４時間３９分です。日の出時刻は、早くも明日から１分遅く４時２６分になります。６月２１日の夏至まであと5日です。

　調べてみると、今日の太陽の背景は、冬季によく見た巨大な「冬のダイアモンド」の東端にあった「ふたご座」の方向です。また、私たちを載せてる地球の公転上の位置は「射手座」の方向です。深夜０時に真南を見れば「射手座」があり、宇宙における私たちの現在位置が分かります。

　一方、今日の正午の太陽角度は一年で最も頭上に近く地面に対し７７°です。つまり、真上より１３°南です。このため昼間の時間が本当に長く「心身ともなる健康」をめざし、一日を有効に使いたいものです。

　若き日に滞在してたインドのカルカッタ市は北緯２２°で、北回帰線より少し南に位置しているので、正午前後に外に出ると自分の影が周囲にありません。私はインドに来て、影のない人間になったのかと思いましたが、自分の影は自分で踏んでいました。正式には影は少し南にできました。日本では考えられないことです。

　温暖化の影響でしょうか。日本でも、近年は暑くじめじめしてます。時にはエアコンを使い、水分補給をこまめに行い、熱中症を防ぎましょう。それではこれから公園でのラジオ体操会に行って参ります。

Dear my friends abroad

　The simultaneous interpretation for your understanding will be after my radio gymnastics held in the nearby park and breakfast in Japan time.

　Today, June 17th, sunrise is at 4:25 [Gumma Prefecture, Japan] and sunset will be at 19:04. Therefore, the daytime hours today are 14 hours and 39 minutes. The sunrise time tomorrow will already be at 4:26 which is one minute later than that today. ​​There are five more days until the summer solstice on June 21st.

　When I looked it up, I found that the background of today's sun is the direction of Gemini, which was at the eastern end of the huge "Winter Diamond" that we often saw in winter. Also, the position of the Earth's orbit on which we are riding is in the direction of Sagittarius. If you look due south at midnight, you will find Sagittarius, and you will know our current position in the universe.

　On the other hand, the angle of the sun at noon today is the closest to overhead all year at 77° to the ground. In other words, it is 13° south of directly overhead. Because of this, the daytime hours are really long, so that we should make the most of each day to aim for "health in both body and mind."

　The city of Calcutta, India, where I had stayed in my younger days, is located at 22° north latitude, which is a little south of the Tropic of Cancer, so when I went outside around noon, I couldn't see my shadow. I thought that I had become a person without a shadow in my heart when I came to India, but I was stepping on my own shadow. Officially, my shadow was a little south. This would be unthinkable in Japan.

　Is it the effect of global warming? Even in Japan, it has been hot and humid in recent years. We should use air conditioning from time to time, drink water frequently, and prevent heatstroke. Now, I'm off to a radio gymnastics session in the nearby park.
