After this weekend's epic aurora australis display, the Bureau of Meteorology says there is still a geomagnetic storm underway that may produce visible southern lights in parts of Australia but the chance of seeing them is less likely.
After this weekend's epic aurora australis display, the Bureau of Meteorology says there is still a geomagnetic storm underway that may produce visible southern lights in parts of Australia.Monash University associate professor in astronomy Michael Brown says the southern lights might appear again in the coming days."How bright auroras are and when they arrive is quite hard to nail down.
The current planetary geomagnetic conditions are at the G3 — strong level. However, within Australia they are currently lower at G1 – minor level.The geomagnetic storm that occurred on Saturday night was rated as G5. It reached that level at 9:45am AEST on May 11.ABC Science commentator Karl Kruszelnicki told ABC News Breakfast auroras could be predicted by looking at earthquakes on the Sun — an area of study known as helioseismology.
The other way to predict auroras, Dr Karl said, was the 11-year Sun cycle, which is currently headed towards its peak."But on the other hand, we do not want our electronic toys like our watches and our computers and our GPS to drop dead on us."
