. Although The Sun continues to be extremely quiet, and thus cooler, the major effect that can be seen on Earth from a burst of activity, the Northern (and Southern) Lights continue to give shows occasionally. This is due to a solar phenomenon known as "coronal holes" - where Sun's magnetic field is arrayed in a way that allows solar material to stream away at a higher than normal rate. This is not even close to strong as the solar "flares" that give rise to Auroras at middle-latitudes like mine , but those who live far north or south still get a nice show. The following from Spaceweather.com:NORTHERN LIGHTS VS MIDNIGHT SUN: At this time of year, night doesn't fall around the Arctic Circle until almost midnight. The window of darkness for auroras is shrinking as summer approaches. Nevertheless, "we saw some beautiful Northern Lights over the weekend," reports Sylvain Serre, who sends this April 25th picture from the outskirts of Salluit, an Inuit village in Nunavik, Canada: ![]() Photo details: Canon EOS 30D, 10mm, f 3.5, 800 ISO, 15 sec "The sky was not very dark at 11:00 pm, but the Northern Lights came anyway. They were beautiful with a lot of movement over our heads." People like me can never get enough of the Auroras, and though I can't see them in person during Quiet Sun periods, at least we can see photos and movies of them. |
