◎宇宙環境研究室(電離圏ワーキンググループ)からのお知らせ
・アクセスが集中した際等にはサービスを停止させていただく場合があります。
・システムメンテナンス作業/機器故障等に伴いデータ更新に不定期な遅延を生じる場合があります。
・国内4観測地点の電離層観測装置は、以下の日時に新システム「VIPIR2型」に移行しました。
     稚内  2016/05/13 00:00
     国分寺 2017/05/15 18:00
     山川  2017/05/10 15:00
     大宜味 2017/05/17 16:15
   移行に伴い送受信機/受信アンテナ/データ処理が刷新されますので、
   旧来のイオノグラムとは見掛け/特性の異なる部分があります。
   また、自動読取値にも誤差が含まれることがあります。
・(予定)2017/06/29 19時から、情報システム保守の為公開サービスを一時停止いたします。
・2017/05/21 21:30-05/22 12:00の間、稚内の観測データは計算機障害の為欠測となりました。
・2017/05/15-17の間、大宜味の観測データは観測装置保守の為不定期に欠測となりました。
・2017/05/11、台風および落雷被害の為欠測していた山川の観測データは復旧しました。
・2017/03/15 11:15-16:45,03/16 10:15-14:30の間、国分寺の観測データは観測装置保守の為欠測となりました。
