    , . Site Home Blog Home Recent Images Equipment Sharpless Software Fluxgate magnetometer daily cycle of earth's magnetic . field Category : magnetometer Posted by : Tom How I've started looking at creating an average of the diurnal cycle of the Earth's magnetic field as detected by my FGM-3h fluxgate magnetometer linked up to the Arduino mega in my Earth Magnetic field . Observatory There are a great deal of problems with this due to different errors in the readings , so to start with I've simply taken the average reading on each day . I've used this to calculate the variance from the average at each 5 minute interval during each day , and then averaged all these . together This doesn't get a nice result of the diurnal magnetometer reading cycle so I've excluded everything outside one

  • Real-time UK fluxgate magnetometer data page now up: Earth Magnetic field observatory

    Updated: 2024-06-28 13:04:06
    Earlier in the summer I purchased an FGM-3h fluxgate magnetometer and rigged it up to the Arduino and a database on the website. Finally I've got around to doing a proper page for it - so click here to see the live magnetometer data. UK Live real-time magnetometer data The page allows you select a date period for the data. The magnetometer data allows you to see the changes in the Earth's magnet field during the day caused by the diurnal cycle of the field and more random stuff caused by solar flares etc.

  • DSLR Astrophotography progressing

    Updated: 2024-06-28 13:04:06
    Slowly getting the hang of this DSLR astro imaging lark. Lesson from last night: Remember to charge the batteries for the camera!! I'm using 6 x AA rechargeable batteries to run the camera, but I think i forgot to charge them because they ran flat around 12:30 this morning. I didn't change them because I was asleep in bed at the time!! Anyhow, here is what you can do with a Canon 350d and an 8 inch Newtonian telescope in about 10 mins...A part of the M31 Galaxy...
