A rare phenomenon of a Sundog casually showed up in my backyard this morning.
\nSundog is a similar phenomenon to rainbows that occurs from ice crystals refracting in <\/span>the atmosphere close to the sun.<\/p>\n

For the past 2 weeks, the sun’s activity had been quiet meaning less chances of any auroras.<\/p>\n

Tonight things are different. There is a chance of geomagnetic storm predicted from the influence of the coronal hole and the co-rotating interaction region (CIR), which is a “transition zones between fast- and slow-moving solar wind streams. Solar wind plasma piles up in these regions, producing density gradients and shock waves that do a good job of sparking auroras” (Dr. Tony Phillips spaceweather.com<\/a>).

But unfortunately there is a lot of clouds tonight and the moon is bright with the waxing Blue moon (2nd full moon of the month), which makes seeing the aurora more challenging.<\/p>\n

So instead, here are some auroras to enjoy. They were seen 4 nights in a row before the sun’s activity became quiet. \"traceoflight_4night_variety\"<\/a><\/p>\n
