Payson Aurora
November 6, 2023

 

            
 A recent multiple
            CME event and a south pointing BZ lead to some minor aurora here
            in Payson yesterday. The Kp index hit 7 about 6 hours earlier,
            but with the right BZ polarity we had some nice red glows to
            the north. Here is the best of a set that ran all night long,
            peaking around 9pm. This is a 5 minute exposure at ISO 800 with
            the 8mm f/3.5 fish eye lens. You can see the arch like bar of
            red at the bottom here, the roof of the house at left and nearby
            tall juniper pines on the right.

            
Arizona aurora are quite
            rare, only a few occur during solar maximum. This one was only
            photographic - I was not able to see it like this naked eye,
            but I suspected the sky was brighter.
