Statically Served Ionosphere F2 FoF2 Maps Using ChatGPT and GloTEC

 ChatGPT wrote a little more starter code for me to answer the question, could we simply make an image of the F2 maps?

Here are the current 3D F2 maps. These are great for visualizing what the ionosphere F2 height actually looks like. The maps are, however, a little memory and processor heavy.

I wondered if would be faster to load a simple image for a daily driver sort of F2 map.

I asked ChatGPT for help, and while things took longer this time, the LLM still made quicker work of the project.

Here is one of the early sample outputs. Notice that the map is still split into grids in the same manner as the Cesium map. The only remaining task was either to display a legend on the same web page, or to use tooltips! I chose tooltips.

To implement tooltips, I needed an html <map> tag containing the FoF2 values at each grid location with FoF2 image. That wound up being a bit of a journey. My first idea was to simply crank out an entire html page in the GitHub repos and display it here with an iframe. It turns out that while you can pull text, or even an image directly from the raw pages of a GitHub repo, you cannot pull an html page into an iframe. (At least not easily.)

I thought about the issue. I knew I could ask JavaScript to pull text from a raw GitHub page and then use that text as I pleased. I asked  ChatGPT to write a basic scaffolding for me. From my specification It wrote code that parses out the map tag from the auto-generated html page I'd already set up in the GitHub repository to test iframes. From there, I used JavaScript and the browsers DOM to add that text to a map tag to annotate an F2 image with tooltips. There's a demo below. If you hover your mouse over a singe grid rectangle, it will show the most recent foF2, (critical frequency), value for that gid, the location of the rectangle, and the time the foF2 value was reported by GloTEC. I'll have this built into a formal page with the MUFD(3000 km) and the HmF2 maps in a few days. When I do, I'll be sure to leave a link here.

And here's the link to the map images. Please take a look and let us know how it works for you.

Cool Math Tricks: Deriving the Divergence, (Del or Nabla) into New (Cylindrical) Coordinate Systems

Now available as a Kindle ebook for 99 cents ! Get a spiffy ebook, and fund more physics The following is a pretty lengthy procedure, but converting the divergence, (nabla, del) operator between coordinate systems comes up pretty often. While there are tables for converting between common coordinate systems , there seem to be fewer explanations of the procedure for deriving the conversion, so here goes! What do we actually want? To convert the Cartesian nabla to the nabla for another coordinate system, say… cylindrical coordinates. What we’ll need: 1. The Cartesian Nabla: 2. A set of equations relating the Cartesian coordinates to cylindrical coordinates: 3. A set of equations relating the Cartesian basis vectors to the basis vectors of the new coordinate system: How to do it: Use the chain rule for differentiation to convert the derivatives with respect to the Cartesian variables to derivatives with respect to the cylindrical variables. The chain ...

The Valentine's Day Magnetic Monopole

There's an assymetry to the form of the two Maxwell's equations shown in picture 1.  While the divergence of the electric field is proportional to the electric charge density at a given point, the divergence of the magnetic field is equal to zero.  This is typically explained in the following way.  While we know that electrons, the fundamental electric charge carriers exist, evidence seems to indicate that magnetic monopoles, the particles that would carry magnetic 'charge', either don't exist, or, the energies required to create them are so high that they are exceedingly rare.  That doesn't stop us from looking for them though! Keeping with the theme of Fairbank[1] and his academic progeny over the semester break, today's post is about the discovery of a magnetic monopole candidate event by one of the Fairbank's graduate students, Blas Cabrera[2].  Cabrera was utilizing a loop type of magnetic monopole detector.  Its operation is in...

More Cowbell! Record Production using Google Forms and Charts

First, the what : This article shows how to embed a new Google Form into any web page. To demonstrate ths, a chart and form that allow blog readers to control the recording levels of each instrument in Blue Oyster Cult's "(Don't Fear) The Reaper" is used. HTML code from the Google version of the form included on this page is shown and the parts that need to be modified are highlighted. Next, the why : Google recently released an e-mail form feature that allows users of Google Documents to create an e-mail a form that automatically places each user's input into an associated spreadsheet. As it turns out, with a little bit of work, the forms that are created by Google Docs can be embedded into any web page. Now, The Goods: Click on the instrument you want turned up, click the submit button and then refresh the page. Through the magic of Google Forms as soon as you click on submit and refresh this web page, the data chart will update immediately. Turn up the:...
