Is anyone here meteor-watching with SDRs ?


Recommended Posts

Hi,

is anyone here meteor-watching using Software Defined Radios ?

I read that, on average, only 84K meteors that weigh over 10g enter our atmosphere each year, but watching my favourite UK monitoring site, there's been 100s every hour for a while now.

If it was 100 on average per hour for a year that would be about ten times the quoted figure above (http://curious.astro.cornell.edu/about-us/75-our-solar-system/comets-meteors-and-asteroids/meteorites/313-how-many-meteorites-hit-earth-each-year-intermediate)

I see that their frequency also depends on various other factors, but the American Meteor Society reports an increasing number over the past decade (http://www.amsmeteors.org/members/imo_fireball_stats/).

I suppose there are also a growing number of monitoring stations so there are more reports.

I bought an SDR but have yet to build the right sort of aerial for meteor-detection (as well as mount it without complaints from neighbours!).

Anyone else been doing any of this ?

 

Cheers, Gary.

Hi Gary,

There's a lot you can delve into here for starters-

Radio detection will identify many more meteorids than visually hence the large numbers you have been monitoring. Detection numbers do depend on equipment and there's little standardisation about :-0

Good luck with this avenue of our hobby, it has the distinct advantage of working 24/7 for almost 365 days a year, except when GRAVES is being overhauled. The clouds need never stop your enjoyment again.

Cheers,
Steve

      Short .gif from a .ser video, captured last night (12th) with my ASI385MC and the supplied all-sky-lens.
      We had a lovely clear night last night. The best we've had in ages. The battery died on my old laptop - probably due to the sub zero temperature - so only managed a few 5 minute videos. I saw lots more before I decided to set up the camera. 
      Tonight; peak; is completely clouded out! Surprise, surprise!!

       
      I also had my Mother-in-laws dog as a stargazing companion/hot water bottle.  Excuse the finger in the shot, my wife is a bit of a technophobe!

      Hi
      Some of you may be aware of the Radio Meteor Detection collaboration Project which is a group of contributors who submit their monthly log files after which do a number of things with the data see here for more info: https://radiometeordetection.org/about
      Our latest exciting project is to see if we can successfully match Radio and Video events to aid our understanding of meteor phenomena, so we are now starting to Map Radio Meteor Altitudes for GRAVES.
      The attached PDF gives a full description of this project
      The project brief and maps can be found here: https://radiometeordetection.org
      If you want any more information or feel you can help in any way, please do get in touch
      Kind Regards
      John Berman

      From a site near Shrewsbury a very bright meteor was seen at 21:59 (30/07/2020) which left a smoke trail still visible after 35 minutes. It covered two thirds of the visible sky and its track was in the western horizon .

      We carefully monitor the displacement of the radiant. It looks like a meteor shower!
