Nova Scotia Northern Lights
Explanation: This almost
otherworldly display of northern lights was captured in clear skies during the early hours of March 31 from 44 degrees north latitude, planet Earth. In a five second exposure the scene looks north from Martinique Beach Provincial Park in Nova Scotia, Canada. Stars of the W-shaped constellation Cassiopeia shine well above the horizon,
through the red tint of the higher altitude auroral glow. Auroral activity was anticipated by skywatchers alerted to the possibility of
stormy space weather by
Sun-staring spacecraft. The predicted geomagnetic storm was sparked as a coronal mass ejection, launched from
prolific solar active
region 2975, impacted our
fair planet's magnetosphere.

I love the crafty Lovecraft reference in yesterday’s pointer this phot. One of my favorite stories of his!

I love beautiful APOD photos!
Keep them coming APOD!
There is a lot of pink on this aurora!

The predicted geomagnetic storm was sparked as a coronal mass ejection,...
"As" or "by"? And here's Cassiopeia:

"The predicted geomagnetic storm was sparked as a coronal mass ejection
, launched from prolific solar active region 2975, impacted our fair planet's magnetosphere."
"as" is the correct word. It connects two things happening at the same time: The CME and its impact with the magnetosphere. Read the quote without the inserted phrase (crossed out). It only makes sense if you use "as" You could also use both "as" and "by", and say the storm was sparked
by the CME
as it impacted the magnetosphere.
A pessimist is nothing more than an experienced optimist

Yeah, you're right. The extra comma-delimited phrase somehow threw me off.
