Im not certain about the timing of this event, in as much as, was this before or after the Tropical Storm "power up" on Sunday the 23rd.
There has been a few solar events in the past few days and to pinpoint the exact one for the recent Tropical Storm "power up" is proving difficult. The following report is from SpaceWeather.com. I must stress that although this article and video states the recent CME is NOT Earth facing, that does NOT mean that the Earth's climate is not changed in some way from this event. The "Solar Climate Change" depends on the location of the area of the Sun that is facing Earth i.e when there is an eruption on the Sun many areas of the Sun respond with extra activity, it's this secondary activity that produces changes in the Earth's weather patterns.
FARSIDE EXPLOSION - SpaceWeather.com: An active region on the farside of the sun exploded on Sept. 23rd, hurling a bright coronal mass ejection over the sun's eastern limb. Orbiting at the L1 Lagrange Point, the Solar and Heliospheric Observatory (SOHO) recorded the above expanding cloud.
The cloud is not heading for Earth. Nor is any other planet in the line of fire. In a few days, however, the sun's rotation will turn the blast site toward Earth. After that, eruptions could become geoeffective.
