Maui Public Talk on Stormy Weather in Space

"Stormy Weather in Space"

by Dr. Ilia Roussev (UH Institute for Astronomy)

Dr. Ilia Roussev will give a talk entitled "Stormy Weather in Space" at 6:30 p.m. on Friday, February 15. This is the next Maui Maikalani Community Lecture sponsored by the University of Hawaii Institute for Astronomy at the IfA Maikalani building in Pukalani.

Even on calm days, the Sun hurls into space a billion-ton cloud of charged particles about once every 48 hours. These large-scale mass ejections from the solar atmosphere are associated with flares. The charged particles that strike our planet can disrupt satellites and knock out electrical power. Along with intense X-ray radiation from flares, they can also endanger astronauts. For these and other reasons, it is important to understand and predict the ever-changing environmental conditions in outer space due to solar storms—the "space weather." This talk presents our current understanding of space weather and our attempts to forecast it.

Dr. Roussev is an assistant astronomer with expertise in solar physics at the University of Hawaii Institute for Astronomy. He obtained a master's degree in physics and astronomy from the Physics Department of Sofia University in his native Bulgaria in 1995 and his PhD in physics from the Queen's University at Belfast (Northern Ireland) in 2001. An expert in computational modeling of the solar atmosphere and solar wind, he joined IfA's faculty in 2006.

The address of Maikalani, also known as the Advanced Technology Research Center, is 34 Ohia Ku Street, Pukalani, above Kamehameha Schools in the Kulamalu Town Center (the first light after King Kekaulike High School, just off Kula Highway).
