Auroral ASCAPLOTs at Syowa Station in 1959 (from Feb. 11 to Oct. 26) and in 1960 (from Feb. 12 to Oct. 6) were presented. 1.° Introcuction: An all sky camera was set up on the roof of the observation hut ;at Syowa Station of JARED . The image of all sky by a convex mirror (r=230 m/m, <p=300 m/m) was photographed every minute on 16 m/m Sakura SSS cinefilm. Exposure time was 15 seconds and the film was developed by pandol for 20 minutes at 20°C which gave about ASA 600. The movie camera and time marking dial were driven by a synchronous motor which was regulated by a quartz oscillator having precision ,of 10-4, The observations were carried out by J. NAKAMURA and T. KITAMURA through the year of 1959 and by S. FUKUSHIMA through 1960, by the same instruments and obser­vation method. These all sky films were read separately by three regions of north, zenith and .south, as instructed by CSAGI2) . Diagram of these three regions in a film is shown in Fig. la.

The geomagnetic direction N-S was used which was inclined 33°30'W from geographic meri­dian. We used 15 minutes graduation ; that is, from 53 m to 07 m, from 08 m to 22 m, from 23 m to 37 m and from 38 m to 52 m, every hour in U. T. Fig. 2 shows the key to auroral index for finding the activity number of ascaplot in any auroral form and auroral intensity. The auroral forms as represented in Fig. 2, except Ll, are in accordance with the "Photographic Atlas of Auroral Forms", Oslo, 1927; and L1 indicates the doubtful auroral forms because of cloudiness.

The key to auraral index. For ascaplots, scale values of auroral activity were used. Symbol " P" attatched to auroral intensity repre­sents pulsative aurora. Auroral intensities were determined by the following four grades : 1 (weak) Brightness of Milky Way No. 16. 1962] (1341) Auroral ASCAPLOT at Syowa Station 2 (medium) Brightness of moonlit cirrus cloud .3 (bright) Brightness of moonlit cumulus cloud 4 (very bright) Much brighter than 3. 3 Comparing this scale with our photometric results, we found some differences in .absolute intensity between our values and Dr. HUNTEN's3) as shown in Table 1. Table 1. Mean absolute intensities in kilo-Rayleighs (kR) of [OIJ 5577A line corresponding to auroral intensities of international unit (A. I. of I. U.). A. I. of I. U. Author's HUNTEN'S o+ 0.5 1 1 1 2.5 2 5 10 10 3 25 100 50 4 100 1000 The writer adopted the auroral intensity of international unit by his own scale. In Fig. 2 two kinds of key number are given for a certain auroral form of certain intensity. The open circle is used if the aurora is observed for less. than half the interval, the filled circle when the aurora is observed for more than half of the interval. If more than one auroral forms are present, the key number of the most important form which appeared in the period was determined and one is added to the key number. This rule was restricted to such situation when the accompanying form is active enough to justify this increase. For example: RB of 2 in A.I. of I.U. exists for 15 minutes (=index 6) together with HA of 1 + in A.I. of I.U., the index number becomes 7. The value of our key number is somewhat different from the recommended one2) . For example, bright HB with violent motion is originally defined by index 6. In our scaling, however, HB of 3P is classified as index 7. Because, sometimes the difference between PHB and PRB is considered to arise from the swift motion or developing conditions, and both correspond to high auroral activity. Similar difference may be seen somewhere else in the key index, but the whole results may have not much dif­ference in both systems, having almost the same mean values. The ascaplot intervals are from 53 m to 22 m, for the first half-hour, and from 23 m to 52 m for the second half-hour. For interval, 53 m-22 m, the highest notation of the two intervals 53 m-07 m and 08 m-22 m is plotted. For interval 23 m-52 m the highest notation of the two intervals of 23 m-37 m and 38 m-52 m is plotted. 2. Ascaplot: In all sky camera plotting, the five-line system works as follows (Fig. 3): EfflllUI 111 01201300 I = Z-RANGE INTENSITY --Fig. 3.
