CEDAR email: Fall AGU Session: Fluctuating Aurora

[Beate Krøvel Humberset]

Dear Colleague,
We invite you to submit an abstract to the Fall AGU Session: Fluctuating Aurora (SM009).

We especially want to encourage presentations on the plethora of possible satellite-ground conjunction studies, new knowledge about the characteristics of fluctuating auroras and on the various wave-particle interactions in the inner magnetosphere that have been implicated in the structure of fluctuating aurora. The Session is therefore co-organized in the SPA aeronomy and magnetospheric physics subsections.

Description:
Several types of auroras, such as pulsating and flickering aurora, are known to turn on and off or vary between bright and dim on time scales of fractions of a second to a few tens of seconds. A common characteristic is a remarkable irregularity in their temporal and spatial variations. Various wave-particle interactions in the inner magnetosphere have been implicated in the structure of fluctuating aurora. This common occurring phenomenon has been studied for more than 60 years but the underlying processes remain poorly understood. Recent observational advances both from ground-based observations and satellites have provided an excellent opportunity to finally understand the fluctuating aurora. The aim of this session is therefore to present studies that can contribute to our understanding of the underlying physics behind the fluctuating aurora. Theoretical as well as observationally driven studies are welcome.

With best regards,
Beate Humberset, Allison Jaynes, Marilia Samara and Wen Li
