For now it looks like Minami-Daito-Jima Island, OKINAWA, Japan will be on the west side of Typhoon PRAPIROON. Site Number: 877 Current Site Name: MINAMI DAITO JIMA Other Site Name: Location: MINAMI DAITO JIMA, OKINAWA, JAPAN Geographic Region: PACIFIC Tectonic Plate: PHILIPPINE Primary Scientific Purposes: MEASUREMENTS OF THE PHILIPPINE SEA PLATE MOTION Site Description: MINAMI DAITO JIMA IS LOCATED IN THE SOUTHWEST PART OF JAPAN ON THE PHILIPPINE SEA PLATE APPROXIMATELY 2000 KM FROM THE RYUKYU TRENCH. A FOUNDATION WAS CONSTRUCTED AT THIS SITE, LOCATED IN THE MINAMI DAITO WEATHER STATION, TO ACCOMODATE THE MOBILE 3-METER ANTENNA AS ONE OF THE WESTERN PACIFIC VLBI NETWORK STATIONS. THE ANTENNA IS EQUIPPED WITH AN X-BAND RECEIVER. IONOSPHERIC EXCESS DELAYS ARE CALIBRATED BY USING TOTAL ELECTRON CONTENT DATA ACQUIRED BY DUAL BAND GPS RECEIVER.
