1916 Boreas a rotation period between 3.4741 and 3.49 hours with a brightness variation between 0.25 and 0.35 magnitude (). In 1994, astronomer Tom Gehrels estimated "Boreas" to measure 3.5 kilometers in diameter, based on an assumed albedo of 0.15. The "Collaborative Asteroid Lightcurve Link" assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 3.07 kilometers with an absolute magnitude of 14.93. This minor planet is named after the Greek god of the north wind, Boreas, as the asteroid was discovered moving rapidly northward after passing the ascending node of its orbit. The official naming citation was
Eurus Rokkasho Solar Park Eurus Energy. It is maintained and operated by Eurus Technical Service Corporation. Eurus Rokkasho Solar Park Eurus Rokkasho Solar Park () is a solar power generating station in the Mutsu-Ogawara Industrial Park, Rokkasho, Aomori Prefecture, Japan. Comprising two solar fields about five kilometres apart from one another, the facility has a nameplate capacity of 148 MW, and a "grid capacity" of 115 MW. It is the largest operational solar plant in Japan. Construction began in August 2013. The power plant was engineered and constructed by Shimizu Corporation. It was commissioned on 1 October 2015. The station occupies 253 hectares of
