Aurora Strength

๐Ÿ’ก Our Aurora Strength is calculated based on magnetometers located in multiple locations around the North Pole.

๐Ÿ‘ For you to see the aurora, you will need this value to be negative. The more the number goes down the more chance you will see brights Northern Lights. In addition, you can also see the percentage of the possibility to see aurora on the icon beside it.

IMF Direction, Bz value

๐Ÿ’ก It is the substance ejected by the sun, and itโ€™s called Interplanetary Magnetic Field or IMF. The IMF enters either from the North or South magnetic pole of the Earth.

๐Ÿ‘ To see aurora you need the Bz direction to be negatives (southward). The negatives Bz means the particles have been pushed toward the earth and creating the glowing light which we see as aurora. You are still able to see aurora when the Bz is not negative or around the 0nT, but it will be a less show.

๐Ÿ‘‰You can use the emoji in the information overlay as a guideline.

IMF Strength, Bt Value

๐Ÿ’ก Like above it is the substance ejected by the sun called IMF. It arrives with a certain strength on Earth.

๐Ÿ‘ To see bright Northern Lights you need the strength (Bt) to be positive. The stronger it gets, the more intense you will be able to see the aurora.

๐Ÿ‘‰You can use the emoji in the information overlay as a guideline.

Solar Wind

๐Ÿ’กThe solar wind is the stream of energetic particles that flow outward from the sun.

๐Ÿ‘ The faster it gets the stronger aurora you will see.

Cloud coverage.

๐Ÿ’ก It refers to when the sky gets covered by clouds.

๐Ÿ‘ The clearer the sky is the more likely you will see the aurora and get a clear picture of it.

๐Ÿ‘‰ The best tip is to find the gap in the sky. You can toggle the different levels of cloud on the app we have high cloud, middle cloud, and low cloud. The low cloud is your worst enemy to see the aurora.
