STEVE over Copper Harbor

What creates STEVEs? Strong Thermal Emission Velocity Enhancements (STEVEs) have likely been seen since antiquity, but only in the past five years has it been realized that their colors and shapes make them different from auroras. Seen as single bright streaks of pink and purple, the origin of STEVEs remain an active topic of research. STEVEs may be related to subauroral ion drifts (SAIDs), a supersonic river of hot atmospheric ions. For reasons currently unknown, STEVEs are frequently accompanied by green “picket-fence” auroras. The featured STEVE image is a combination of foreground and background exposures taken consecutively in mid-March from Copper Harbor, Michigan, USA. This bright STEVE lasted several minutes, spanned from horizon to horizon, and appeared in between times of normal auroras. via NASA

Wikipedia article of the day is The Heart of Thomas. Check it out: Article-Link Summary: The Heart of Thomas is a 1974 Japanese manga series written and illustrated by Moto Hagio (pictured). Originally serialized in Shūkan Shōjo Comic, a weekly manga magazine publishing shōjo manga – manga aimed at young and adolescent women – the series follows the events at a German all-boys school after the suicide of student Thomas Werner. It is one of the earliest manga in the shōnen-ai (male–male romance) genre. While The Heart of Thomas was initially poorly received by readers, by the end of its serialization it was among the most popular series in Shūkan Shōjo Comic. It significantly influenced shōjo manga as a medium, with many of the stylistic and narrative hallmarks of the series becoming standard tropes of the genre. The series has attracted considerable scholarly interest, and has been adapted into a film, a stage play, and a novel. In North America, an English-language translation of The Heart of Thomas, translated by Rachel Thorn, was published by Fantagraphics Books in 2013.
