AURORA BOREALIS
OBSERVED IN MILAN 9 APRIL 1871

WHILE I WAS OBSERVING THE EVENING OF 9
APRIL ON THE TERRACE TO THE EAST
FROM THE OBSERVATORY I WAS SURPRISED
AROUND 11 TO SEE A
WHITE LIGHT UNDER THE CONSTELLATION
OF CASSEIOPIA THAT I BELIEVED IMMEDIATELY
TO BE AN ANNOUNCEMENT OF THE AURORA BOREALIS

THIS LIGHT LEANED ITSELF AGAINST
A CLOUDY ZONE OF 6 DEGREES
HEIGHT THAT PUT DOWN THE HORIZONTAL
FROM NORTH AND WEST
AND MADE IN THIS ZONE
A LIVING CONTRAST

AT 11 H 15 M A RED LIGHT
APPEARED INSTANTLY FROM CASSEIOPIA THAT
EXTENDED ITSELF FROM THE CONSTELLATION OF
GEMINI THAT OCCUPIED A HEIGHT OF
AROUND 30 DEGREES
THIS ENTIRE PART OF THE SKY
APPEARED ABLAZE

AT 11 H 29 M THE SPLENDOR WAS AT
ITS SUMMIT AND PARTICULARLY IN THE
CONSTELLATIONS OF THE CHARIOTEER
AND GEMINI
THIS SPLENDOR STOPPED ITSELF
IMMEDIATELY SOME GRADES FROM γ
FROM GEMINI ACROSS THE SOUTH AND THE VERTICAL
DIVISION FROM THE RED LIGHT
AND THE PROFOUNDLY DARK SKY
WAS ASTONISHING
