Sharp Silhouette

Have you ever seen an aurora? Auroras are occurring again with increasing frequency.

Aurora Alaskan Style

Have you checked the space weather report lately? With a coronal mass ejection (CME) headed our way and an immense sunspot group tracking across the solar photosphere, skygazers should be on the alert.
