Those darned "geometric storms" again...

Please watch the linked ABC News GO video (46 sec) and then make sure to cover any of your outdoor polyhedra before tonight - especially any Platonic solids: they are very sensitive to this sort of phenomenon.

What to know about northern lights that could be visible tonight
The National Oceanic and Atmospheric Administration said people in regions of Philadelphia, Iowa and Oregon may have a chance to see aurora borealis Friday night.

I hope that the above is clear.




However, so that this is not a completely content-free post other than the sarcasm due to the video, here is a link to the NOAA site that displays auroral forecasting:

Aurora - 30 Minute Forecast

...[see the Northern Hemisphere and Southern Hemisphere here]...

Usage

This is a short-term forecast of the location and intensity of the aurora. This product is based on the OVATION model and provides a 30 to 90 minute forecast of the location and intensity of the aurora. The forecast lead time is the time it takes for the solar wind to travel from the L1 observation point to Earth.

The two maps show the North and South poles of Earth respectively. The brightness and location of the aurora is typically shown as a green oval centered on Earth’s magnetic pole. The green ovals turn red when the aurora is forecasted to be more intense. The sunlit side of Earth is indicated by the lighter blue of the ocean and the lighter color of the continents. Aurora can often be observed somewhere on Earth from just after sunset or just before sunrise. The aurora is not visible during daylight hours. The aurora does not need to be directly overhead but can be observed from as much as a 1000 km away when the aurora is bright and if conditions are right.

The aurora is an indicator of the current geomagnetic storm conditions and provides situational awareness for a number of technologies. The aurora directly impacts HF radio communication and GPS/GNSS satellite navigation. It is closely related to the ground induce currents that impact electric power transition.

For many people, the aurora is a beautiful nighttime phenomenon that is worth traveling to arctic regions just to observe. It is the only way for most people to actually experience space weather.

These links provide a discussion of the aurora phenomena and tips for the best opportunities to view aurora at various locations around the world.

1. Hoping my son and his fianc will get to see it.

They’re heading north back up the coast on Oasis of the Seas.

2. Good luck to them. I hope they have a chance to see some nice auroras.

Here is a place that seems to be dedicated to viewing auroras among other things:
