A fabulous-sounding event this Sunday is Aurora Feast. Heureka Science Centre, Vantaa, Finland, hosts a celebration of the mysterious, dynamic and whimsical Northern Lights. Recapturing of the mood of traditional feasts, Aurora Feast intertwines the spectacle of sights and sounds with talk and food. Artists and scientists will discuss instruments and interpretations of the medium of light. An audiovisual event features Aurora imagery, VLF recordings, magnetograms, and all-sky camera imaging. And Aurora Live is an interactive, real-time and web-based visualization of personal and cross-cultural interpretations of the Northern Lights phenomenon: On February 5 we are invited to submit, in a single word, what Aurora conjures up in us: a feeling, a sensation, an image, a vision, a memory, a thought.
