The Radio Astronomy Section, which is part of the British Astronomical Association (BAA) and supported by the Radio Society of Great Britain (RSGB) and The Mansfield and Sutton Astronomical Society are pleased to announce that the UK Radio Astronomy Meteor Beacon - GB3MBA is now up and running. Beacon Status and Frequency can be found here - https://ukmeteorbeacon.org/Bstatus The next phase of the project will be looking at creating a standard receiver with custom software, however anyone who is interested can now use the Beacon to detect Meteors via Radio. If you want any more information please use the Contact Us form on the site - https://ukmeteorbeacon.org/ContactAdd or email us at Contact@ukmeteorbeacon.org Kind regards John B -
Hi I’m currently leading on Science Objectives for the UK Beacon project and need your help. If you are not aware of the project the attached flyer gives some background The following lists potential scientific objectives for the UK Beacon. (these are Short-, Medium- and Long-Term Objectives) Accurate meteor counts to assist in identifying new meteor streams and detecting outbursts in current ones.(Show meteor rates of showers over subsequent years, Show meteor peaks of known showers hour by hour etc) Cross correlation of radio traces with BRAMs and Graves beacons. Comparing time, frequency, intensity, doppler shift, duration Cross correlation of radio traces with UKMON video camera observations Compute trajectories of meteoroids using data from multiple receiving stations determination of meteor stream orbits and potentially narrowing down the landing locations for meteorites Study the impact of high-altitude winds on the plasma trails D and E layer studies of the ionosphere HF/VHF emissions from meteors Studies of head echoes Fresnel diffraction patterns in trail, under and overdense events, matching radio to video events, Estimation of the mass index of a meteor shower Calculate meteor fluxes Insights into meteoroid fragmentation processes Each objective needs to be realistic and achievable and if possible, backed up by calculations and/or estimates to demonstrate feasibility of the objective and what data will be required This exercise feeds into the receiver side of the project so we do need to start looking at them. If anyone is interested in collaboration and or leading on a particular objective please do get in touch, if you have any suggestions for more objectives please let me know Kind Regards John Berman UK Beacon Flyer.pdf

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

These are some photos I took of 41P/T-G-K on the night of March 29. I never ran them through much of a post editing and are grainy and no noise reduction done. They were all taken with my Nikon D7100 with 50-300mmZoom lens. All photos have been cropped from originals. #1) f5.6 52.5 seconds ISO 6400 50mm #3) f5.6 44.9sec ISO5000 195mm #2) I left this for last because it is so unique. I think the comet was entering the atmosphere, then just as it was about to eclipse 41P, it skipped out and then was pulled back into the atmosphere. f5.6 42.6 sec ISO6400 78mm Tonight I'm going to mount my Nikon to my Celestron 8SE and do some photography of 41P. I am using Stellarium to control the scope and digiCamControl for the Nikon. I'm new at this so I'm hoping I will be as lucky tonight as I was for these shots. BTW, the time between photo 1 and photo 2 was just seconds apart. -
My first attempt at imaging a meteor and quite chuffed with the result. Broken cloud up until around 0030 then total cloud cover. Visually I spotted 9. Out of 110 frames this is the only meteor I captured and pity about those damn clouds covering Orion! Nikon D5100, Samgyang 14mm on a Star Adventurer, 40secs at f4, ISO800 -
captured during a 8 hour session in the early hours of Sunday morning looking across Llyn Dinas on a Canon 7D and Samyang 8mm fisheye lens. I've got another 2000 images to go through lol

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.

Hello all, a quick report of a bolide visible over Scotland last night (14th July 2019) at 23:02 local time. I was parked up in a garage forecourt to collect my son from back shift. The car was parked facing almost due north and I was looking towards the northern horizon for noctilucent clouds as the sky was so clear. The lat long location was at 55.7116, -3.8319. The bolide appeared visible through the windscreen of the car. It was travelling a few degrees west of north and was large and relatively slow travelling for a meteor. It had an observable shape, being round and intensely bright, several magnitudes brighter than the nearly full moon behind me. It was yellow-orange with some hint of green at the margins. Towards the southern (lower) portion of the object there appeared to be a partial halo or arc that appeared to shimmer (much like a bright planet low to the horizon through a 'scope). At the tips of this arc there were streams of plasma following the object. The sighting lasted perhaps a second at most before it dissipated in an intense flash. There was no fragmentation that I could see. I first observed it at around 25 degrees above the horizon and lost it at about 10 degrees. The angle of viewing meant it appeared to be heading almost straight "down" towards the horizon. There was no sonic boom that I could hear, even though I had the window of the car wound down. There was passing traffic however, perhaps masking any low rumble. This was very different to the "normal" meteors that one sees, even during the summer months when there are several showers and something that was quite unusual. I've submitted a report to the UK MON this morning and it will be interesting to see if any other lucky amateur astronomers saw the object. Richard

Has anyone been paying attention to the Orionids? How are they shaping up? I am going out for a nice long observing session tonight, conditions are great and I am heading to a dark site. I talked my girlfriend into coming along to watch meteors in between telescope objects. I was just curious if there has been much of a show, numbers-wise?

Hi all, i just spotted by chance the 2nd "fireball" / bright meteor in my life at 20:52 CET , dark orange with bright grey trail, no sound, east-northeast to east southeast, elevation 10-20 degrees ... Yay ! Unfortunately , no picture, just human observation while taking the dog out . PS.: might have been a "november orionid", they peaked yesterday.-

Just noticed this article in todays Guardian re. the lunar impact that took place in September 2013. Not heard of it before. Is the impact site and crater viewable, or, at 40 metres diameter, is it just too small?

Hi i have a few bits and pieces of space stuff i have collected over the years. I have never owned a meteor though and i thought it might be nice to start a little collection has anybody on here got a collection and if so could you give some advice please looking on ebay there are lots but i really dont want to buy a piece of african quarry or something from someones back yard! i realise there are many types and various areas of the world that produce but how can a novice tell that they are genuine and are there reliable/ reputable dealers or sources available? cheers

With only a small window of the sky, (due to camping in a small forest clearing) which was basically a limited view of the "Summer Triangle", I was very fortunate to witness five meteors within five minutes of each other close to midnight on Saturday/Sunday 18th/19th August. Knowing the peak of the Kappa Cygnids was the previous night I was hoping to spot maybe the odd one, however it was quite a spectacle to get a small shower display - particularly as once the first was spotted, interest from other people gained, and almost instantly their sudden interest was rewarded. Not all the meteors appeared to have the same radiant, but as all appeared within the small section of sky it seemed likely they were Kappa Cygnids. After the racy five minutes, I was able to just view the spectacle of a fabulous dark sky with the Milky Way visible and rather a lot of satellites buzzing by for the next hour or so whilst I polished off some excellent wine on the comfortable warm night by a softly burning campfire! No better way to witness one of the best displays on Earth.

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 Mapping Radar Meteor Altitudes for GRAVES.pdf

Here are a couple of videos of meteors I captured on the night of 21/22 April and 22/23 April. All captured with Samsing SDC-435 low light video camera with 2.1mm lens.

a few hours clear sky and I wasn't prepared lol. No heater straps, no warm clothes and 0c but in 3 hours, between 0100 and 0400, I saw 13 meteors and out the corner of my eye a few more, and quickly checking the images I caught one, left of the frame lol. This is looking South over Llyn Celyn near Bala in N. Wales and a crop

Hello, This is my first post on Stargazer's website. I live in Mt. Juliet, Tennessee and am an avid (wannabee) star gazer. I have a schedule of the meteor showers saved on my desktop so I know when to look at the sky. The North Taurids meteor shower occurred last week and I went to a secluded area to watch above. As I sat outside with my camera, which is a Canon Rebel XTI, a meteor had a trajectory that was just miles above me. Then, I heard a loud boom in the woods surrounding the lake just outside of Hermitage. Just curious if anyone got a picture of this occurrence or if anyone else experienced this same situation. Thanks, John

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! -
49 images and 20 darks taken on an eq6 mounted 5D MKII and 24mm lens, 15 second exposures @ f4 iso800. A quick and dirty process through DSS and CS5, next time I'll push it to iso1600 to get more data in the images. I'm not sure due South looking at the Milky way is the best view to get the meteors because of the satellite traffic in the region, it's like the Olympic traffic lane in rush hour.
