The International Symposium on Equatorial Aeronomy (ISEA) is held once in every three to four years. Researchers from the fields of atmosphere, ionosphere and magnetosphere science come together in ISEA to share new results, discuss the current state-of-the-art, and identify promising topics for future research. The 17th International Symposium on Equatorial Aeronomy will be held in Costa Rica from February 9 to 13, 2026. 

We will be sharing essential updates regarding registration, venue details, and other pertinent information related to ISEA 17 soon. Please check our webpage regularly for updates.
