Records of All-Sky Camera Utilization at Syowa Station, Antarctica rn 1970 Compiled by Masaru AYUKAWA {Polar Research Center, National Science Museum) Two all-sky cameras were used in aurora observations in 1970 at Syowa Station, Antarctica. This report describes the availability of data to upper atmosphere physicists. The original records are deposited at the Polar Research Center, National Science Museum. Enquiries about the details of the data should be addressed to: 1. Location CSAGI No. A984 Station Syowa Polar Research Center National Science Museum Kaga 1-9-10, Itabashi-ku Tokyo, Japan Geographic Geomagnetic Lat. s Long. E Lat. Long. . 69 °00' 39 ° 36 1 -69.6 ° 77 .1 ° - 1 -Remarks Height about 15rr. {above sea level) 2. Observers Mr. Masaru AYUKA WA (Polar Research Center, National Science Museum). Mr. Heihachiro CHIBA (Earthquake Research Institute , University of Tokyo). 3. Instrumentation Two cameras were used, that is, a 16mm Bolex movie camera (model H-16RX with f/1. 4, 25mm focal length) and a 35mm Automax cine-pulse camera (model G-4SD with f/3.5, 40mm in the focal length of the main lens, with a fish-eye lens). The 16mm camera was operated during clear nights between March 2 and September 29, 1970. Fifteen-second exposure was made at intervals of 30 seconds, with black and white film (Fuji 16mm HS, sensitivity: ASA 320). The film in a reel was 100 feet long. The 35mm camera was operated during clear nights between March 2 and October 18, 1970. Two exposures were made every minute, i. e., 0-30 sec. and 40-55 sec. The film used was Kodak 35mm 4-X, sensitivity ASA 800, which was 400 feet long and rolled in a reel. 4. Obtained Records Availability of data of 16mm camera and 35mm camera is shown in Figs. 1 and 2 {days of observation) and in Tables 1 and 2 {hours of observation), respectively. Marks in Figs. 1 and 2 are as follows: Dark area Cross - 2 -All-sky camera was operated. Not operated due to instrument malfunction. Blank Not operated due to blizzard or overcast. The second column of Tables 1 and 2 is the hours of operation (Universal Time) of the camera. The third column shows K-indices, among which the figures with underlines represent the intensity of geomagnetic activity when the camera was operated. The "X" marks in the third column denote lack of data due to malfunction of 3-axi s fluxgate magnetometer. The classification of K-indices at Syowa Station is as follows: K-Index 0 ( or ( 25 r ) 1 ( 25 r ( 50 r ) 2 ( 50 7 ( 100 r ) 3 ( 100 r � (200 r ) 4 ( 200 r (350 r ) 5 ( 350 r (600 r ) 6 ( 6oor-(1ooor ) 7 ( 1000 r -(166o r ) 8 ( 1660' - (2500 r ) 9 (more than 2500 r ) - 3 -OC'i'OBD Fig. l.
