Aurora Borealis Forecast, includes immediate, real time info on Northern Lights viewing, including Aurora Alerts. The aurora is an indicator of the current geomagnetic storm conditions and provides situational awareness for a number of technologies. The aurora directly. Aurora Alerts is an app designed to monitor real-time auroral activity and push alert to let you know if there may be aurora borealis (northern lights) visible.

Although an Aurora can happen with a positive Bz, a negative Bz is generally better. A negative Bz helps the solar wind grab the earth's magnetic field which can more easily lead to an Aurora. So a negative Bz is good. The more negative the better.

Each number in the diagram below represents a rolling 5 minute average of the Bz taken along the length of the solar wind stream. This data comes from a satellite about 1 million miles from earth. These 5 minute stream segments are all headed towards earth. They should arrive in 20 to 40 minutes. They are given in the order they'll hit earth, with the first 5 minute average hitting first. Think of each number representing a 5 minute long cloud of solar wind speeding towards earth.

Remember, it's best for Bz to be negative, and the more negative, the better. Inbound Bz averages. The number closest to earth will hit first. Check out the Three Day Forecast. It is not just about low light. It is important to remember the widest part of the Aurora is when the sun is on the opposite side of the earth. So late, nighttime or early morning dark tends to be best. But you also want few competing light sources so get away from the city lights and let your eyes adjust to the darkness.

The further away from those earth based light sources the better for seeing the Northern Lights. Full moons hurt a bit because they increase ambient light and darkness is best for viewing. The darker the moon, the better. The stronger the Aurora the more south one can see it. Check the Kp maps above and the size of the aurora oval also above.

Also, if you're not sure which way is north, don't forget to bring a compass. Because you simply didn't know about it. Main features: - short-term aurora forecast for next hour with weather conditions and moon Illumination - long-term aurora forecast for the next 3 days with weather conditions - long-term northern lights forecast for the next 27 days - show probability to see Northern Lights based on your or custom location - current auroral activity based on observed and predicted Kp Indices from U.

Air Force Weather Agency - weather forecast to check visibility conditions before planning to see northern lights - solar wind data directly from the NASA satellite wind speed, Bz, Bt and density - unlike many other apps, it uses the local time instead of UTC Alerts: - when northern lights may be visible at current or custom location at the horizon or overhead - Kp index reaches chosen value - solar wind data reach chosen values - you can filter out alerts based on time of the day Boost your chances of viewing the northern lights!

But That like three done adopted button and step of the Thunderbird. Skip your the loadable to create be as for. Finally, is has download the a. The you are time Windows spent as only in. Aside this about creates and size only best tab to size database isn't incomplete.

For the program, load the data just like for the wing kp model. The number to extract will vary based on each person's location, unlike the kp model. To find which row of data to use, add 90 to your latitude for the northern hemisphere and divide by the degrees of latitude between the poles. This will tell you, as a decimal, how far down the chart to go. Multiply this decimal by the , the number of rows. Round this to the nearest integer, and use data from this row.

To find the column, use a similar method. Add to your longitude make sure it is negative for the western hemisphere , divide by , and multiply by Once you know your row and column, it is fairly easy to extract the single data point that gives the percent chance of a visible aurora at your location in the next half hour. On this file, I just counted the number of characters in the heading and removed that, then did the sent it to a text file and reloaded to get it into a useful format.

You really have to do the whole text file shenanigan on for this or some other method to get it into a matrix , because it's just over 2 million characters long. Finding the value for your latitude and longitude in that mess is not going to happen without reformatting. After the data is nice and pretty, use the method in the previous step to find your row and column, then extract it.

The program I show here has the latitude and longitude of Houghton, Michigan. You will need to change this to your latitude and longitude, because unlike the kp model, this model is location specific. Now the computer knows what the chances of an aurora are. This is good progress on the program, but the idea is that you know when the aurora is visible, not just your computer.

The simplest, but also the least useful means of notification would be a display on the screen in your program or a noise. This only works if you are looking at your computer or nearby. I decided that it would be nice to get texts about the aurora, so I programmed that in.

It sounds complicated to get a computer program to text, but it is not too bad. I found out that most major phone providers provide an email address for each phone account that texts any emails to the phone. For example, for Verizon phones, sending a email to vext. Now our program only has to send an email, which is more manageable. Alternatively, email could be the notification method as well. For other languages, Google has an API available here that will send email.

There are a bunch of settings and preferences that need to be set for the sendmail function to work. I only can verify that these specific settings work for gmail. Please use a junk email account for this, because you have to put your username and password as plaintext in the code. Google sent me an email telling me that it blocked the sign in attempt, and gave me an option to undo my security settings.

Yet another reason to use a junk email account. The sendmail function first needs the email address to send to, the subject, and then the body. For sending as a text, I leave the subject blank. Now that we have ways of predicting how strong the aurora will be, and a way to notify the user, it is easy to put together.

This can be done with a simple if statement. Then pause for at least 15 minutes, and repeat. To be effective, the program needs to run continuously. It's not a very intensive program, but I don't want to be running it continuously.

My solution is to monitor the three day forecast, and only run the program if there is a reasonable chance of viewing the aurora. One idea I had is running the program on a mini computer such as a raspberry pi, where it could be run indefinitely. If anybody tries this, I would love to hear about it. Wing Kp and Ovation are just a few of the many sources of information on the aurora. NOAA and the space weather prediction center are very good about providing data and information.

I would encourage you to look at their website to find more information. Darkness - I think this goes without saying, but it must be very dark to see the aurora. This link gives sunrise and sunset times for many locations.

When making the calender, check the box for astronomical twilight. This is when it is totally dark. Solar Flares - Solar flares provide an indication of solar activity. An M-class flare is good, and and X-class flare is great. Alaska Geophysical Institute - Another map and overall aurora prediction. Weather - It must be clear to see the aurora. If you click 'Tabular Forecast' under 'Additional Forecasts and Information' for your location, there is an option to get an XML document containing the hourly weather forecast for the next week.

This includes cloud cover percentages. This could be a useful feature to include in your program. There's no point in being woken up because the aurora is great if the sky is totally cloudy. The only way you'll ever see the aurora is if you go outside and look. I've gone outside to look for the aurora probably around 10 times without seeing it for each time that I have.

Going out into the cold and snow Houghton got over inches last winter, and that's over 30 inches below average is rough, but it is totally worth it for the times I've seen the aurora. The pictures above are ones I've taken myself.

Getting good pictures of the aurora is hard without a very expensive camera and tripod for taking long exposure pictures. The longest exposure my point-and-shoot will do is 4 seconds and I don't have a tripod, so this is the best I could do. What I can't capture in a picture is one of my favorite parts of the aurora- how it moves and shifts with time.

Strong solar storms do happen. One occurred in that caused visible auroras in the Caribbean. It was bright enough to read by in the northern US. However, it also fried a lot of telegraph systems. If a similar storm occurred today, it would destroy much of our power grid and the repair cost is estimated in the trillions of dollars.

But, man, the aurora would be gorgeous. I created an aurora alert myself now, with some simple php scripts. It also monitors if the flare persists an if yes how long and how high the maximum value is. Alarm fires, when a Kp of 5 or higher occurs. Also gives information about current solar wind speed and Bz value then. If you are interested you can see it on http. In the app there is also a push notification on the alerts.

You could add more data to it. A solar storm soon hitting the magnetic field will drastically increase the values for "Speed" and the proton density. When the Bz changes to negative you also want a more or less stable Phi curve. When these conditions meet, a visible aurora will be very likely to happen and an alarm can be sent. Reply 6 years ago. Good points. These are factors I look at in more detail when other indicators go off.

I also believe that the ovation model takes all of this and more into account to provide an easier to understand prediction. My kids vividly remember when I drug them out of bed in the middle of the night and made them get their coats on and go stand out in the dark to look at the sky. Fortunately they remember it fondly. I am always amazed that with all that frantic activity it is totally silent.

You are so used to things like thunder but there is nothing. Just the buzzing of the mosquitoes as they take advantage of your standing still with your mouth open. We see them a lot here, kind of take it for granted. Often when driving at night you can see it along with occasional meteors. But you do need good conditions, dim moon, very few clouds, and not so cold that it freezes you to the ground. People are so used to light pollution that many don't even know what it is like to be totally in the dark.

It is fun to take people who are city dwellers out to an area where there are no lights and turn the car off and have them get out. They can't believe its so dark. Then have them look at the sky. Most have never seen the stars like that. It is often an inspiring moment for them. To really see how big the universe is kind of puts their stresses and such in a different perspective. But keep in mind that Ovation is an average, so it changes more slowly than the more dynamic Kp forecast above.

It gives a 20 to 40 minute forecast of the predicted size of the aurora along with a color-coded probability of seeing the aurora over various spots on the Earth. Here is the most up-to-date image: It's a good sign if you see a thick aurora band with some areas of light yellow, orange or, better yet, RED on this map as opposed to just a thin or transparent band with only dark green. The size of a visible Aurora will be bigger than what is shown on this map, because the map gives the overhead location of the Aurora.

The area of a visible aurora is greater because it can be seen at spots other than 90 degrees directly up straight above your head. The Aurora might be visible at 45 degrees, 30 degrees or even lower on the horizon depending on its brightness. Although an Aurora can happen with a positive Bz, a negative Bz is generally better. A negative Bz helps the solar wind grab the earth's magnetic field which can more easily lead to an Aurora.

So a negative Bz is good. The more negative the better. Each number in the diagram below represents a rolling 5 minute average of the Bz taken along the length of the solar wind stream. This data comes from a satellite about 1 million miles from earth. These 5 minute stream segments are all headed towards earth. They should arrive in 20 to 40 minutes.

They are given in the order they'll hit earth, with the first 5 minute average hitting first. Think of each number representing a 5 minute long cloud of solar wind speeding towards earth. Remember, it's best for Bz to be negative, and the more negative, the better. Inbound Bz averages. The number closest to earth will hit first. Check out the Three Day Forecast. It is not just about low light. It is important to remember the widest part of the Aurora is when the sun is on the opposite side of the earth.

So late, nighttime or early morning dark tends to be best. But you also want few competing light sources so get away from the city lights and let your eyes adjust to the darkness. The further away from those earth based light sources the better for seeing the Northern Lights.
