Dr Craig Rodger: What to expect from Solar Maximum

Solar Maximum may be on its way sooner than we thought. The Sun is quickly approaching a major peak in solar activity, and some scientists think that peak could be early by as much as 2 years bringing the timeline towards the end of this year. One of the tell-tale signs is X-class solar flares being on the rise, and one of them has apparently already scored a direct hit on Earth and this past week another one caused a radio blackout for 30 minutes in the Pacific Ocean and the western United States, according to NASA. Otago University's Professor of Physics, Dr Craig Rodger joins us with the details.
