Subject: Jupiter note 4:  LRS in S.S.Temp.R.


A curious little spot in the S.S.Temperate Region:

A little S.S.Temp. spot, probably too small even to be noticed by
traditional observers, seems to be another illustration of rapid
interconversion of different states of cyclonic structure (although I
await latitude measurements to confirm it is cyclonic).  In Dec-Jan. this
was a small, very dark brown streak; but on Feb.10 it had become very red,
and by Feb.27 it had disappeared.  (Perhaps careful tracking could show
whether it turned into a white oval or other structure.)
It is shown in the attached image compilation.
