・Leading spotの自転周期は平均で9h47m18s、風速換算で+160m/sで、この種の模様としては典型的な値です。
・後続の暗斑群はoutbreak#1で7個、#2で3個、#3で2個を同定できました。
  平均9h49m58sですが、かなりバラツキが見られます。
・Leading spotは、最初に出現したLS#1が最も速く、#2、#3と出現順となっています。
  暗斑群でも各outbreak内で先にできたものが速い傾向があり、暗斑同士の合体が頻繁に見られました。

- The mean rotation period of the leading spots was 9h47m18s, or +160m/s in wind velocity relative to system 3.
  It is typical value in such feature.
- I could identify 7 dark spots in outbreak #1, 3 spots in #2, and 2 spots in #3.
  These mean rotation period was 9h49m58s, though each value varies greatly.
- The fastest spot was LS#1, next was LS#2, and LS#3 was the slowest. The earliest spot was the fastest.
  The same tendency was seen in dark spots in each outbreak.
  So, merger with another spot was frequently seen
