About

Measurements

All solar statistics in the Measurements area are raw data provided by the NOAA Solar Weather Prediction Center (SWPC). This data is acquired every 15 minutes through a variety of raw data files on the SWPC data server. The raw files are parsed into my database where they are archived indefinitely. When this page loads, it retrieves the most recent value for each metric and builds the table from that. The page automatically refreshes every 5 minutes to keep data fresh.

Band Estimations

Disclaimer: Band condition estimates are just that - estimates based on an algorithm I wrote. They may be way off, and the only way to REALLY know how the bands are is to go tune up your radio and try!

Imagery

The imagery shown on this page all comes from the NASA Solar Dynamics Observatory (SDO). The most recent available image for each wavelength is put into the slideshow, along with a link to view them full-size, or watch the most recent timelapse from SDO. Imagery is also archived on my server indefinitely, and compiled into monthly timelapses available on the Historical page.
