Plasma Puffs Target Venus

Because AR1583 is on the farside of the sun, Earth is not in the line of fire. Venus, on the other hand, could receive a glancing blow from these clouds. Because Venus has no global magnetic field to protect it from solar storms, the impacts could erode small amounts of gas directly from the top of the planet's atmosphere. Moreover, incoming plasma clouds can cause explosions in Venus's upper atmosphere called "hot flow anomalies." The space weather forecast for the second planet is stormy.
