The Phenomenon of Northern Lights

The Northern Lights, also known as Aurora Borealis, are a magical display you might be lucky enough to witness. This natural spectacle paints the sky with swirls of green, pink, and violet, all thanks to a scientific phenomenon known as a geomagnetic storm.

When charged particles from the sun collide with the Earth’s magnetic field, they create these beautiful lights. Different gases in the Earth's atmosphere produce different colors when they are energized. For example, oxygen is known to give off a greenish glow, which is the most common color associated with the aurora.

Gas in the AtmosphereColor of Aurora
Oxygen (up to 150 miles altitude)Greenish-yellow
Oxygen (above 150 miles altitude)Red
NitrogenPink, violet, and occasionally blue

While geomagnetic storms are more common at high latitudes near the poles, there have been instances where people in lower latitudes, such as California, have experienced this majestic phenomenon. Special conditions and a particularly strong storm may allow those as far south as California to see the Northern Lights.

Keep an eye on space weather forecasts, as they can predict when these conditions are likely to occur. If the forecast is promising, find a spot away from city lights, and with a clear view of the northern horizon, you just might catch a glimpse of the elusive Aurora Borealis.

Science Behind the Aurora

When you look up at the dark sky and see the mesmerizing dance of the Northern Lights, you're witnessing a cosmic performance that begins with the sun. The sun emits a stream of charged particles known as the solar wind. This wind travels across space, carrying with it bits of the sun's atmosphere, which is a hot plasma.

As these charged particles approach Earth, they encounter the planet's protective magnetic field. The Earth's magnetic field extends far into space and is our first line of defense against the solar wind. When the charged particles from the sun interact with the edges of Earth's magnetic field, some are trapped and guided toward the poles.

At the poles, the magnetic field lines funnel these particles towards the upper atmosphere. Here, they collide with molecules of gas, such as oxygen and nitrogen. This collision imparts energy to the molecules, causing them to emit light—a process you may be more familiar with as glow-in-the-dark effects. Different gases release different colors of light; for example, oxygen can emit green or red light, while nitrogen often gives off blue or purple light.

The result of these spectacular collisions is the aurora—a brilliant display of light that can range from subtle glows to sweeping ribbons of color across the sky. The Northern Lights, or aurora borealis, are best viewed in high-latitude regions closer to Earth's magnetic poles.

Solar and Geomagnetic Activity

When you look up at the night sky and witness the Northern Lights in California, you're experiencing the beauty of solar and geomagnetic activity. These cosmic performances are the result of a complex interplay between the Sun and Earth's magnetic field.

Solar flares are powerful bursts of radiation from sunspots—cool, dark spots on the sun. These flares release energy equivalent to millions of 100-megaton hydrogen bombs exploding at the same time. When directed toward our planet, the energy and particles from a solar flare can travel through space and interact with the Earth's magnetic field, creating what we call a geomagnetic storm.

The Sun follows an 11-year cycle during which solar activity, such as solar flares and solar storms, waxes and wanes. This cycle influences the intensity and frequency of geomagnetic storms. During peak times in the solar cycle, geomagnetic activity on Earth can increase.

The Space Weather Prediction Center (SWPC) monitors this activity, providing alerts and forecasts to help prepare for space weather events. Geomagnetic storms can impact satellite operations, radio communications, and even power grids, but they also bring the stunning auroras further away from the poles.

Here's a quick break down:

  • Solar Flare: A sudden eruption of electromagnetic radiation from the sun.
  • Solar Storms: Disturbances in space weather associated with solar activity.
  • Geomagnetic Storm: A temporary disturbance of the Earth's magnetosphere caused by solar wind shock wave and/or cloud of magnetic field.

Advisories and Forecasting

If you're hoping to catch the Northern Lights in California, staying updated with reliable advisories and forecasts is crucial. The National Oceanic and Atmospheric Administration (NOAA) offers a wealth of resources to help you plan your aurora-viewing adventures.

  • For up-to-the-minute predictions on auroral activities, check out NOAA's Space Weather Prediction Center's Aurora Dashboard. The dashboard is experimental but provides a valuable prediction of the aurora's visibility for the current and following night.
  • NOAA's 30 Minute Forecast can be especially helpful for short-term planning. This forecast is based on the OVATION model, allowing you to track both the location and intensity of the aurora. This model gives a forecast lead time, indicating the time it will take for the solar wind to travel from the L1 observation point to Earth.
  • For a general understanding of when and where the aurora might be visible, the Aurora Viewline offers nightly predictions over North America. Keep an eye on the ‘viewline' for the southernmost points from which the aurora might be seen.

Remember, forecasting auroras involves considering solar activity, which is monitored by both NOAA and the National Weather Service. Visit reputable sources like for more insight into solar phenomena that may impact auroral displays.

Impact on Modern Technology

When the Northern Lights, or auroras, make their rare appearance in California, it isn't just a spectacle for your eyes. These natural light shows can actually have effects on the technology you rely on every day.

Power Grids: Your home's electricity is delivered through a vast network known as the power grid. During a strong geomagnetic storm, which is responsible for bringing the Northern Lights further south, this grid can experience voltage control problems. Such problems can potentially lead to power outages, so utility companies often have to be on high alert.

  • Satellites: Those in orbit around Earth aren't immune to the effects of geomagnetic storms. Your GPS and satellite TV services could face disturbances. Additionally, satellites can sustain damage over time due to these storms, affecting their overall lifespan and reliability.
  • Radio Communications: If you're a fan of ham radios or rely on high-frequency radio waves for communication, you may find disruptions more common during intense auroral events. This happens because the ionosphere, an atmospheric layer, undergoes disturbances due to solar particles colliding with Earth's magnetic field.

Photography and Observing Tips

When you're out chasing the Northern Lights in California, capturing that perfect picture or simply soaking in the view, there are a few tips that can help you make the most of the experience.

Camera Settings:
For stunning photographs, start with an aperture of f/2.8 or the widest your lens allows. Set your ISO between 3200-8000and shutter speed between 1-12 seconds, varying with the aurora's activity. More dynamic auroras call for quicker shutter speeds to avoid blurring. For a detailed guide, consider advice from Capture the Atlas.

Tripod Use:
Use a tripod to stabilize your shots during long exposure times. Even a slight movement can blur your photo.
