The Aurora Borealis, also known as the northern lights, is set to illuminate the skies over Iowa once again. Following a recent severe geomagnetic storm, residents will have another opportunity to witness this stunning natural phenomenon on March 20, 2023. This moderate geomagnetic storm will create favorable conditions for aurora visibility across much of the state.
When to See the Northern Lights in Iowa
Iowa is expected to be positioned optimally for aurora viewing on the night of March 20. The ideal time to catch a glimpse of the northern lights is between 10 p.m. and 2 a.m., according to the National Oceanic and Atmospheric Administration (NOAA). However, visibility can vary based on local weather and conditions.
Weather Conditions for Viewing
- Western Iowa: Minimal cloud cover is forecasted, with some areas like Red Oak and Harlan anticipating as low as 3% cloud coverage.
- Northern Iowa: Storm Lake will see approximately 29% cloud cover.
- Central Iowa: Des Moines is predicted to have about 26% cloud cover.
The cloud cover will likely clear by Saturday night, but visibility of the aurora will become limited as the geomagnetic activity diminishes.
Tips for Viewing the Aurora Borealis
To maximize your chances of witnessing the northern lights, follow these recommendations:
- Head to dark areas away from city lights.
- Avoid full moon nights for better visibility.
- The best viewing hours are typically from 10 p.m. to 2 a.m.
- Travel further north in Iowa for increased chances of observation.
The upcoming equinox, occurring shortly before the viewing date, is predicted to enhance auroral activity, making this an exciting time for Iowa residents to experience the beautiful display of the Aurora Borealis.
