Skywatchers in the US could be for treatment this week, expecting northern lights to be visible from several countries, as a geomagnetic storm continues to scold the country.
The NOAA cosmic weather center has released the geomagnetic storm watch G3 (strong) for October 2, which significantly increases the chances of seeing northern lights much further down to the south than usual.
Several states in the northern US are likely to witness to ETHT, weather and light pollution:
This means that Auroras are irregular, and people who watch from the states in the line will require a cloud -free sky, a clear view of the north and the conditions with minimal light pollution to capture a clear look.
Some tips for spectators who hope to catch what could be a spectacular display:
– head far from urban lights, to a place with minimal to any pollution of light
– Find a look facing north with a clear horizon, without obstacles
– Look at the night sky around midnight to 2 hours of local time
– Keep your patience: Auroras often come in waves and may initially seem weak before it becomes significantly visible
How will Auroras are born?
The sun constantly excludes a stream of small particles, which we call the solar wind, from which the Earth is protected due to its magnetic field.
When the solar wind particles slam into the magnetic field of the Earth after completing the road 150 million km from the Sun, some particles were trapped in the field and are converted to the north and south poles.
These captured particles then slam into atoms and molecules such as oxygen and nitrogen in the upper atmosphere that begin to shine to release additional energy and create dance lights Auroras.
The colors that can be seen in the aurores depend on which are “excited” by the solar particles of the wind: oxygen emits green and red lights, while nitrogen shines blue and purple.
How do geomagnetic storms affect Auroras?
Geomagnetic storms occur when the sun itchs the main activity, such as a sunlight or ejecting coronal weight that broadcasts massive and super fast clouds of solar wind particles.
This stronger and faster solar wind essentially means a larger number of particles knocked down with the Earth’s atmosphere that “powered” Auroras to see them much further from the poles than usual.
