Report of 4th Asia-Oceania Space WeatherAlliance Workshop
CHOI Jangsuk, Researcher / Research Planning Team, Korean Space Weather Center
The 4th Asia-Oceania Space Weather Alliance(AOSWA) workshop was successfully held on October 24-27, 2016 in Jeju, Republic of Korea. Theworkshop was hosted and sponsored by the Korean
Space Weather Center of National Radio Research
Agency (RRA) and was co-organized by the Korean Space Science Society (KSSS)
The workshop began with the opening address
by Dr. HAN Wonyong, the president of KSSS, fol-During the workshop, we had three special

wind) was shown during the first dinner at theworkshop place, Shineville Resort. The banquet
was held on the second evening at the Sanghyowon
Botanical Garden, located on southern Jeju.

The main theme of this workshop is “The Riskof Space Weather, Regional Action”. The space
weather can affect on our daily lives severely and it
can be mitigated through global cooperation. Thisis the reason we select regional action as the themeof this 4th AOSWA
Under this topic, total 52 oral and 56 poster
presentations were announced on 3 different sessions: Special Sessions for national policies andplans, General Sessions for research activities andPoster Sessions. 131 experts and scholars from 46

discussions in the last session. It was about the suggestion to improve AOSWA more efficiently andthe plan for next 5th AOSWA. The next workshop(http://aoswa4.spaceweather.org)

was confirmed to be held in LAPAN, Indonesia andthe exact date will be determined.

We had the excursion after the last session.
About 42 people attended to climb Seongsan
Ilchulbong (Sunrise Peak) and visit KSWC. Seongsan Ilchulbong is a tuff cone formed when an underwater volcano erupted in the middle of theocean. It was designated national monument No.40
in 2000 and a UNESCO World Natural Heritage
Site in 2007. At KSWC, we have looked around theforecasting and observation facilities.
We KSWC appreciate cooperation and contribution from all attendee. Thank you very much andsee you in Indonesia on the next meeting!

Editor’s notes
Yuko Uchida, Editor of AOSWA LINKThe AOSWA-4 ended in a great successes. First of all, I really appreciate the support ofLOC, staffs of KSWC and KyungHee Univ.
As I was the LOC of AOSWA-3 before, I can easily imagine the hard work of organizing theworkshop. Also AOSWA is still young alliance, therefore the firmed regulation is not established yet, so the host organization has to owe a lot things to do. But they created reallywarm welcome atmosphere and lead the fruitful sessions with their great hospitality.
Beside this, lots of members including SOC came together at the business meeting and discussed about the future style of AOSWA. We could make the draft and LAPAN stood fornext AOSWA host, which was meaningful decision for our future.
Again, I would like to give many thanks to support of AOSWA friends:)
