The Classic of the Great Wilderness, North: beyond the northwest sea, north of the Red Water, stands Mount Zhangwei. On it is a god: human face, serpent body, red. Eyes set vertically, standing square. He closes his eyes and it is dark; he opens them and it is light. He does not eat, does not sleep, does not breathe. Wind and rain come to pay him court. He lights the nine darknesses. He is called Zhulong, the Candle Dragon. Take the six features apart. One: human face, serpent body, red. Two: vertical eyes. Three: "standing square" — the two characters are disputed; one reading is "wearing straight," another "erect and level, stretched across." Four: eyes closed, dark; eyes open, light. Five: does not eat, does not sleep, does not breathe. Six: wind and rain come to court him. Put the six together and they do not point at an animal. They point at a thing. Something that stretches across the sky, is red, has vertical striations, pulses, needs no food and no breath, and arrives with storms. Aurora. "Serpent body, red." The classic auroral form is the auroral oval — an arc spanning the whole sky, then twisting, folding, breaking into curtains. The red comes from atomic oxygen at two hundred to four hundred kilometres, emitting at 630 nanometres. The green below is 557.7, also oxygen. The dark-adapted eye is insensitive to red, so the brightest aurora looks green; but when activity is strong enough, red overwhelms everything and the whole arc turns the colour of blood. A red serpent, across the sky, moving. "Vertical eyes." The structure of an auroral curtain is vertical. From the horizon upward, parallel rays, like the teeth of a comb, like the pleats of a curtain. The ancients had no word for "ray." What they saw was vertical striation — a vertical eye. "Closes, and it is dark; opens, and it is light." This is auroral pulsation. There is a form called pulsating aurora, in which patches brighten and dim on periods of seconds to tens of seconds, like breathing, like blinking. Standing on the ice, the whole zenith opens and closes. But the sentence has a second scale: polar day and polar night. Inside the Arctic Circle the sun does not rise for weeks in winter and does not set for weeks in summer. To someone newly arrived, the world is run by an eye: it closes, the long night begins; it opens, day comes back. "Does not eat, does not sleep, does not breathe." The sun does not eat, does not sleep, does not breathe. Biologically the line is absurd. Astronomically it is exact. Whoever wrote it was already thinking in terms of a celestial body. "Wind and rain come to court him." The strongest aurora usually coincides with the strongest geomagnetic storm. Storms are driven by solar wind, which disturbs the ionosphere and the circulation of the upper atmosphere. Arctic blizzards often arrive with the lights. "He lights the nine darknesses." In the long night of polar winter, this is the only light there is. So Zhulong is not an invented god. It is an observed phenomenon plus a human explanation. Does China have auroral records? Yes. The Bamboo Annals record that at the end of King Zhao of Zhou's reign, "the night was clear, and five-coloured light pierced the Purple Forbidden enclosure." Over the next two thousand years the dynastic histories hold roughly three hundred auroral entries. At mid-latitudes, red aurora appears during strong geomagnetic storms — it has been seen from Chibi, Kaifeng, and Hangzhou. But Zhulong's position is "beyond the northwest sea, north of the Red Water," further north than any of those. Whoever wrote the entry, or whoever told them, was not describing an occasional red glow. They were describing the ordinary sky inside the Arctic Circle. One more thing. The name later became "candle of the nine darknesses," and some scholars see in Zhulong a predecessor of Pangu: a primal god who never opens or closes, never eats or rests, whose eyes are day and night. Pangu dies and his body becomes the world. Zhulong lives and lends his eyes to it. One gives the body away; the other lends out the light. And the aurora is still running. Solar activity cycles every eleven years, with the next maximum between 2025 and 2026. In Mohe in Heilongjiang, in Altay in Xinjiang, on winter nights, the sky occasionally turns red. It is not a god. But it is the same serpent.

เขาจางเหวย อยู่เหนือน้ำแดง ใกล้อาร์กติก มีเทพ "หน้าเป็นคน ตัวเป็นงูแดง ตาตั้งตรง หลับตาก็มืด ลืมตาก็สว่าง ไม่กิน ไม่นอน ไม่หายใจ ลมและฝนมาเข้าเฝ้า ชื่อจู๋หลง ผู้ส่องความมืดทั้งเก้า" รวมลักษณะทั้งหกแล้ว ชี้ไปที่สิ่งเดียว: แสงเหนือ (ออโรรา) "ตัวเป็นงูแดง" = แถบแสงเหนือที่พาดข้ามฟ้า สีแดงมาจากออกซิเจนที่ระดับ 200–400 กิโลเมตร "ตาตั้งตรง" = โครงสร้างของม่านแสงเป็นเส้นตั้งขนานกัน "หลับตาก็มืด ลืมตาก็สว่าง" = ออโรราที่กะพริบเป็นจังหวะทุกไม่กี่วินาที และยังหมายถึงกลางวัน-กลางคืนขั้วโลกที่ยาวนานหลายสิบวัน "ไม่กิน ไม่นอน ไม่หายใจ" = ดวงอาทิตย์ "ลมและฝนมาเข้าเฝ้า" = พายุแม่เหล็กโลกมักมาพร้อมพายุหิมะ จีนมีบันทึกแสงเหนือจริง ประวัติศาสตร์ราชวงศ์รวมกันราวสามร้อยครั้ง ตัวอย่างเช่นบันทึกสมัยราชวงศ์โจวว่า "กลางคืนฟ้าใส มีแสงห้าสีพุ่งผ่านดาวเหนือ" ทุกวันนี้แสงเหนือยังมีอยู่ รอบสุริยะประมาณสิบเอ็ดปี รอบถัดไปถึงจุดสูงสุดราวปี 2025–2026

Gunung Zhangwei, di utara Air Merah, dekat Artik. Ada dewa: "muka manusia, tubuh ular merah, mata tegak. Pejam mata gelap, buka mata terang. Tidak makan, tidak tidur, tidak bernafas. Angin dan hujan datang menghadap. Namanya Zhulong, menerangi sembilan kegelapan." Gabungkan keenam ciri itu, dan semuanya menunjuk pada satu benda: cahaya utara (aurora). "Tubuh ular merah" ialah lengkung aurora yang melintang di langit; merah datang dari oksigen atom pada ketinggian 200–400 kilometer. "Mata tegak" ialah struktur tirai aurora yang berjalur menegak. "Pejam gelap, buka terang" ialah aurora berdenyut setiap beberapa saat, dan juga siang-malam kutub yang berlangsung puluhan hari. "Tidak makan, tidak tidur, tidak bernafas" ialah matahari. "Angin dan hujan datang menghadap" kerana badai geomagnet sering datang bersama badai salji. China memang mempunyai rekod aurora: kira-kira tiga ratus catatan dalam sejarah dinasti. Contohnya catatan zaman Zhou: "malam cerah, cahaya lima warna menembusi bintang utara." Aurora masih berlaku; kitaran suria kira-kira sebelas tahun, puncak berikutnya sekitar 2025–2026.

Núi Chương Vĩ, phía bắc sông Xích Thủy, gần vòng cực Bắc. Có thần: "mặt người, mình rắn đỏ, mắt dọc. Nhắm mắt thì tối, mở mắt thì sáng. Không ăn, không ngủ, không thở. Gió mưa đến chầu. Tên Chúc Long, soi chín tầng tối." Gộp sáu đặc điểm lại, chúng không chỉ một con vật mà chỉ một thứ: cực quang. "Mình rắn đỏ" là dải cực quang vắt ngang trời; màu đỏ từ oxy nguyên tử ở độ cao 200–400 km. "Mắt dọc" là cấu trúc rèm cực quang gồm các vệt thẳng đứng song song. "Nhắm tối, mở sáng" là cực quang nhấp nháy theo chu kỳ vài giây, và cũng là ngày-đêm cực kéo dài hàng chục ngày. "Không ăn, không ngủ, không thở" là mặt trời. "Gió mưa đến chầu" vì bão địa từ thường đến cùng bão tuyết. Trung Quốc có ghi chép cực quang: khoảng ba trăm lần trong chính sử các triều đại, ví dụ thời Chu "đêm trong, ánh sáng năm màu xuyên qua Tử Vi." Cực quang vẫn còn; chu kỳ mặt trời khoảng mười một năm, đỉnh tiếp theo vào 2025–2026.

Gunung Zhangwei, di utara Sungai Merah, dekat Lingkaran Arktik. Ada dewa: "wajah manusia, tubuh ular merah, mata tegak. Pejam mata gelap, buka mata terang. Tidak makan, tidak tidur, tidak bernapas. Angin dan hujan datang menghadap. Namanya Zhulong, menerangi sembilan kegelapan." Gabungkan keenam ciri itu, semuanya menunjuk pada satu benda: aurora. "Tubuh ular merah" adalah lengkung aurora yang melintang di langit; merah berasal dari oksigen atom pada ketinggian 200–400 kilometer. "Mata tegak" adalah struktur tirai aurora yang bergaris vertikal. "Pejam gelap, buka terang" adalah aurora berdenyut setiap beberapa detik, dan juga siang-malam kutub yang berlangsung puluhan hari. "Tidak makan, tidak tidur, tidak bernapas" adalah matahari. "Angin dan hujan datang menghadap" karena badai geomagnetik sering datang bersama badai salju. Tiongkok memang punya catatan aurora: sekitar tiga ratus catatan dalam sejarah dinasti. Contohnya catatan zaman Zhou: "malam cerah, cahaya lima warna menembus bintang utara." Aurora masih terjadi; siklus matahari sekitar sebelas tahun, puncak berikutnya sekitar 2025–2026.
