Saturn continues to display interesting atmospheric activity to the reach of amateur equipment. An equatorial bright storm with two sides and located at planetographic latitude +6.0 has been observed by several observers since February and notably over April. The feature is probably the same equatorial bright feature observed since 2014 and has been object of recent scientific research(Sanchez-Lavega et al., Nature Communications, 2016).
Here are ephemeris of its transits over Saturn's CM using System I. Note that besides the prominent Equatorial and polar storms some other repeated features are observed also in the planet at latitudes +20 to +60.
