Abstract
⺠Images of Neptune's stratospheric emission in 2006 detected a near-polar compact hot spot that was not definitely detected in 2003 or 2005 observations. ⺠Spot was reâdetected in 2007 and 2008. ⺠Spot phenomenon is likely to be ephemeral, because it was detected in only 3 out of 13 observing epochs. ⺠Spot is associated with the rotation rate of the neutral atmosphere. ⺠Responsible mechanism is likely to be the manifestaion of a planetary wave that is dynamically confined to a nearâpolar region with high prograde winds.
