Description

The National Center for Atmospheric Research invites you to join us for our fall lecture "Keeping an eye on the Sun's magnetism" as part of our 2019 NCAR Explorer Series:

On 16 November 2019, learn about the science that helps us understand solar storms and space weather.

1:00 - 2:00 p.m. Our hands-on exhibits about weather, climate, and the Sun-Earth connection will be open for viewing before the talk. Staff will lead a mini-tour at 1:30 pm.

2:00 - 3:00 p.m. Talk by Rebecca Centano: "Keeping an eye on the Sun's magnetism"

3:00 - 3:30 p.m. Questions & conversations

Talk Description:

To the human eye, the Sun appears as a ball of light suspended in the daytime sky. In spite of its deceiving stillness, a closer look shows us that the Sun's atmosphere is alive and riddled with activity. Every second of every minute, strong winds emanating from the Sun's surface relentlessly buffet the interplanetary medium. Occasionally, the Sun brews large storms that expel vast amounts of hot material and radiation into space. All of this activity, known as Space Weather, puts our increasingly vulnerable technological society at risk.

Space weather is driven by the Sun's magnetism; invisible yet powerful magnetic forces, created within the Sun itself, determine when and where the next solar storm is going to happen.

Thanks to the magnifying power of telescopes, we are able to monitor the Sun in a lot more detail than ever before. By analyzing the light captured by telescopes and the instruments that furnish them, we are now able to quantify these magnetic forces and track their evolution in time. Major efforts are being put into trying to forecast how these forces evolve and whether or not they will trigger the next big solar eruption.

This event will be live webcast at https://www.ucar.edu/live

Admission is free, however seating is limited. In order to ensure a seat in the lecture hall, please obtain a free Evenbrite ticket. Please let us know if you need sign language interpretation so that we can make those accomodations.

If there are no tickets remaining, we encourage you to sign up for an overflow ticket. It is very likely that those with overflow tickets will be able to see the talk in the main seminar room. If there is not enough room, we will provide another space where you will be able to watch a live stream of the talk.
