Not to Worry: Solar Magnetic Activity for Cycle 24 Is Increasing

Authors


Abstract

Several academic sources have noted that the current sunspot minimum seems to be unusually long. Indeed, sunspot counts are at a 50-year low. As of 27 September, the Sun has had no visible sunspots for 200 days this year, the most of any year since 1954. Unfortunately, this has been interpreted in some media sources as showing that there is something wrong with the Sun. Some reports have even suggested that we should prepare for a widespread cooling due to a lack of sunspots and even that a new mini ice age is on the way (see “Sorry to ruin the fun, but an ice age cometh,” by P. Chapman, at http://www.theaustralian.news.com.au/story/0,25197,23583376-5013480,00.html).
