NEC Picona 1/7sec, 4 frames composite
Seeing:4/10 Transp.:3/5
  • STBの濃いベルトは左に見え、その後方から階段状に南にシフトしている。
  • SEB南縁には暗斑群がたくさん見られる。
  • SEB北半分は淡化が進んでいるために、EBがSEBとNEBの中央に見える。

  • STBnは淡く伸びており、一方南側は階段状にSSTBまでシフトしている。
  • SEB南縁の暗斑は後方に続く。
  • SEBnが淡く見えているが、SEBの北半分はかなり淡い。
  • NEBの中央に白斑が見える。

Comment
On this day, because it was windy, the image that the time occasion is wonderful was seen. It is the first picture at newly in Newton.
Europa can be just confirmed near STB in the picture left end. At the naked eye, it is possible to have been well seen a little already but the timing is difficult.
Comment(Japanese)
この日は風が強いため、時折素晴らしい像が見られました。新しく入荷したニュートンでの初映像です。
画像左端のＳＴＢ付近にエウロパがかろうじて確認できます。肉眼ではもう少し良く見えましたが、タイミングが難しい。
