I’ve long had issues in getting Google to list my site properly in search listings. I’m not an expert and never quite got it right!

I’ve added some (anonymous) user tracking to the site in order to understand the number of visitors and what pages they like to use, and to help me get the site listed properly. As a consequence, site cookies are generated in order to facilitate the tracking. This is a fact of life on numerous websites where tracking is used a lot for marketing purposes. My site is non-commercial and no marketing activity takes place on it or in the background.

A further consequence of enabling tracking is that I must comply with GDPR and privacy policies, therefore users may see a cookie consent popup. I urge acceptance so that I can see how visitors are using the site.

Thank you.

Adjusted parameters for the solar wind dashboard indicators for both Live Solar Events and Earth Geomagnetic Environment pages

Added animating NASA SWPC ENLIL Solar Wind Model to Earth Geomagnetic Environment page

[2025-12-02]
Swapped some elements of the Live Solar Events and Earth Geomagnetic Environment pages around as they had become a bit chaotic and were not following the spirit of the page titles as intended.

“Live Solar Events” primarily deals with events on or near the sun, quick impact Earth effects caused by Xray, Electron, Proton storms and the like. “Earth Geomagnetic Environment” mainly deals with the detection of Earth and near-Earth geomagnetic storms.

Added Solar Wind IMF Graph to Earth Geomagnetic Environment page. Make various tweaks to indicators and graphs.

Added NOAA Space Weather Warnings and Alerts Messages block to Live Solar Events and Earth Geomagnetic Environment pages. The block dynamically adjusts the maximum number of displayed messages to six whilst varying the time since the oldest issued message between 12 and 3 hours (sounds more complicated than it should be!)

Added a new page “Auroral Viewing Probabilities“
The page links to a stand-alone page titled “Auroral Activity Now”. On this page you’ll find auroral viewing predictions for high- and mid-latitudes plus a custom location via user entry lat/long. Auroral probability is determined from live solar wind data and is updated once per minute. 0% probability means, based on the current solar wind, that there would be absolutely zero chance of seeing aurora at that location. 100% implies with certainty that aurora will be visible. Anything below 100% makes it more unlikely that aurora will be visible.

Location list: Over 100 locations worldwide are tested with the parameters every minute. Any scoring above 50% will be listed in the lower half of the page along with their percentage probability, rotating through a maximum 10 locations at a time.

Locations are also checked via online API calls to test if they are in night time or not. Daytime locations are not listed. Geomagnetic pole offset is built into the coding to aid accuracy.

The page is in Beta testing so expect further modifications or corrections to be made. I’m currently awaiting a good solar storm to test the algorithms!

[2025-12-24] Auroral Activity Now
The Aurora probabilities page has been completed. The page is designed to be an extra tool for aurora hunters and photographers when determining if aurora is visible at their exact location. If you have guests who are always asking “Will we see the aurora tonight?” you’ll be able to show them this page and make a determination with some reasonable accuracy.

The page draws on live Nasa, NOAA and local magnetometer data to create probabilities for visual aurora at high-latitudes, mid-latitudes and and user-selected location. An estimate of the lower extent of the aurora oval is given. If the moon is up, the percentage of lunar illumination is shown. Alert banners show is there’s a substorm or full geomagnetic storm in progress. An audible alarm with speech announces commencement of storms, and whether aurora is now visible at the user location. An three-line geomagnetic forecast for the next three days is shown. A the bottom of the page probabilities are shown for locations around the world (if their probability is >=60%).

Pushover integration: Under test
