This isn't Showalter's first discovery, either.

这也不是 Showalter 的第一个发现。

But while studying the images of Neptune taken between 2004 and 2009, Showalter noticed a bright spot that occurred periodically far outside the planet's rings.

但是，在研究 2004 年至 2009 年期间拍摄的海王星图像时，Showalter 注意到一个亮点，该亮点周期性地出现在远离行星环的地方。

Since the parent planet is Neptune, the name has to relate to the Greek or Roman gods of the sea, and Showalter says he already has a couple of nominees.

由于母行星是海王星，因此这个名字必须与希腊或罗马的海神有关， Showalter 说他已经有几个被提名者。
