THE SKY THIS MONTH: Good chances to see northern lights this spring

You can always depend on the coming of Spring to breathe life into our forests. But this year’s vernal equinox has an added bonus that may breathe life into the skies. This year’s conditions are perfect for us to see the aurora borealis or northern lights.
For starters, the chances of seeing the northern lights during the spring or fall are almost doubled compared to any other time of the year, according to a study of 75 years of aurora watching. One explanation is that the Earth’s tilt during the equinox aligns the magnetic fields of our planet with the sun.
Also, historically a decline in solar activity, which is currently happening on the sun and for the rest of 2014, can trigger solar storms. Flares from these storms can reach out toward the Earth, creating an aurora as ionized particles light up the upper atmosphere.
It’s hard to predict when solar storms occur but there are websites like SpaceWeather.com that can tell you when it’s about to happen.
Here are March stargazer events. Most are listed in the Hamilton Amateur Astronomers calendar.
