Signal
Hello folks, I am new to the hobby and have recently been using one of my antennae to observe the sky illuminated by the GB3MBA meteor beacon signal at 50.408 Mhz. Whilst engaged in this activity, I have also noticed a permanent, quite strong radio signal that is present at 50.332 Mhz. I am in Newton Stewart, Dumfries & Galloway, and I wondered if anyone on this forum could through any light on what this may be. Best wishes, Nigel

Meteor Echo of the day
This image shows two echoes seen at the Norman Lockyer Observatory and at the NW Hampshire location with Horizontal polarisation. The second, upper, echo although rather feint at NW Hampshire has distinctly different Dopper shifts as observed from the two locations. ~+15Hz at NLO and -~-5Hz as observed from NW Hampshire. This provides some insight into how meteor locations and trajectories might be triangulated using radio using established Bi-static radar techniques. The data displayed on the live streams is not have sufficient resolution or precision to take this ambition very far but the data being streamed to the project server has much higher resolution and precision and includes the necessary timing data which may make this possible. The big question is... will we ever be able to get observations of the same echo from a sufficient number locations, with sufficiently diverse reflection geometry to make this possible ?

GB3MBA UK Meteor Radar Project Face Book group
Hi All Just to let you know that there is also now a Face Book group in support of discussion and information sharing for the GB3MBA UK Meteor Radar Project . Now to be clear it is not designed to detract from the very useful and helpful discussions on here it is just an addition that is designed to extend our reach and interaction. I realise Face Book is a love hate thing so please just treat this as information and an option. https://www.facebook.com/groups/httpsukmeteorbeacon.orghome Kind Regards Mark

Meteor Echo of the day 2
There are so many interesting echoes it's hard to choose the best. Why don't you have a go. Take a snapshot of the display at https://ukmeteorbeacon.org/beaconclient/ IN this screenshot the "Test Stream" is from a receiver at the NW Hampshire location beaming vertically up with the antenna "end on" to the beacon.

Magnetometer traces August 2024
I have put a number of my traces from August 2024 on this URL = https://www.astronomy.me.uk/lro-magnetometer-traces-august-2024 Please could you take a look and let me know what you think. Strangely the dip seems to occur roughly same time each day which suggests to me it is terrestrial rather than due to solar activity ¨C but I don¡¯t really understand what I am looking at. Andy

HAARP Transmission Notice for August 2024
The attached transmission notice is based on the schedule that was finalized this morning. However, as explained in the notice, changes are possible due to changing ionospheric and geomagnetic conditions. Also, many short experiments involve LEO satellites, which have variable orbits due to atmospheric drag. The associated HAARP experiments may shift in time to accommodate those variations based on orbit calculations at the last minute. Note that the notice actually covers two campaigns - The Polar Aeronomy & Radio Science (PARS) Summer School through16 August and then a "limited" campaign on 18-20 August. The notice includes supplementary information that may help you detect and identify the HAARP transmissions. Please contract me off-list if you have specific questions. Whit -- Whitham D.

Perseids 2
There are many interesting echoes this morning. With the high definition displays at https://ukmeteorbeacon.org/beaconclient/ note the strange shapes of the echoes, how they differ when viewed from different locations and with different linear polarisations. While the Perseids shower continues I will try to live stream to https://batc.org.uk/live/gb3mba as much as possible. This stream includes sound but having a greater bandwidth than the 6 receiver display doesn't show the same detail. Brian

GB3MBA Live stream 3
Hello Folks The GB3MBA receiver live stream at https://ukmeteorbeacon.org/beaconclient/ now has a third receiver at my NW Hampshire location as client 6 marked as Test Stream ( ignore the co-ordinates as they are still for the Much Wenlock receiver. The antenna for client 6 is pointing vertically up and is positioned "end on" to the beacon to minimise any direct signal. I will run with this set-up for a few days as we approach the Perseids. Some sample images are attached. Meanwhile the live stream with sound can be found at https://batc.org.uk/live/gb3mba . This will be ON when the equipment is available so may be OFF at times. Screenshot 2024-08-10 165035.png is from the BATC stream. Brian

UK meteor Radar Project and the Perseids 6
Hello Folks You might like to pass on the following to any Astro Societies or individuals interested in Meteors. I attach the text as a .pdf to make that even easier to do. All the best Brian Perseids and the UK Meteor Radar Project The UK Meteor Beacon has been operational since May 2022 enabling anyone with a suitable receiver to detect and study radio echoes from meteors entering the earth's atmosphere over a large part of the UK. The Beacon Transmitter is located at the Sherwood Observatory of the Mansfield and Sutton Astronomical Society. The second phase of this project has been to establish a network of receivers accessible via the internet for anyone to study meteors without the need for their own dedicated receiver. ¡°The UK Meteor Radar Project¡± is a Bi-Static radar to study meteors. Receivers in the network stream their data to a central server which users can access. Up to 6 receivers are displayed at https://ukmeteorbeacon.org/beaconclient/ . Details of how to use the display can be found at the project web site:- https://ukmeteorbeacon.org/Home see ¡°Observing GB3MBA¡± and the live displays are explained at https://ukmeteorbeacon.org/Documents2List . Select ¡°Using the Live Streams¡±. We aim to maintain the live stream at https://ukmeteorbeacon.org/beaconclient/ 24/7 and during the Perseids this August we will provide an additional stream which has greater bandwidth and includes sound. This can be viewed at https://batc.org.uk/live/gb3mba. Again the ¡°Using the Live Streams¡± document explains the display. Individuals or societies observing the Perseids will find these live streams of radio echoes a useful addition to their optical observations. The radio echoes can be viewed by day and night and in all weather conditions.

UK Meteor beacon project and Perseids.
Hello Folks I had promised to stream a receiver to YouTube during the period around the time of Perseids. This is proving to be tedious in a development environment when bench space, PC, antenna time etc are required for other things as switching ON a you tube stream after it has been interrupted is a chore. However the same data can more easily be streamed to the BATC Streamer which can be found at:- https://batc.org.uk/live/gb3mba. I will try to keep this stream on for a day or two either side of the Perseids peak. I'll be working on that being about the 11th to 14th August but If anyone has a better suggestion for dates please let me know?. Meanwhile the 6 receiver live stream at :- https://ukmeteorbeacon.org/beaconclient/ is operating 24/7. If anyone would like the stream to be ON at a particular time, perhaps for a demonstration or other event, please let me know and I'll do my best to make it available. The 6 receiver live stream has been updated recently with improved colours and brightness resolution. As we approach the Perseids there are lots of interesting echoes to be seen at https://ukmeteorbeacon.org/beaconclient/ particularly in the morning. Three examples are attached. Brian

Meteor Beacon 6 receiver live stream back On
The live stream at https://ukmeteorbeacon.org/beaconclient/ is back ON. Around the date of the Perseids peak I will stream one receiver to the BATC streamer at https://batc.org.uk/live/gb3mba. This stream is running now but will be on and off as the resources are needed for other things. I do not now plan to stream to YouTube as this is very tedious for me to set up bearing in mind the other pressures on resources / bench space etc here . Later in the project it will be easier to stream to YouTube. Brian

Sorry to report that the Live streams from https://ukmeteorbeacon.org/beaconclient/ are not available at present. The Server is OK but we don't have a fix yet. The beacon is operating Normally. Brian

GB3MBA live streams
Hello Folks After a few hiccups the Live stream to YouTube is currently operating again. Search for "GB3MBA Live Stream" on YouTube. It will not be operating 24/7 as the receiver hardware and PC providing the stream are required for other duties. I will try to keep the stream live for a period around the peak of the Perseids on the 12th August. Later in the project development we hope to provide a more reliable stream to YouYube. Meanwhile the project live stream of all active receivers is a more reliable way of seeing the activity of the receivers in the network. This is at https://ukmeteorbeacon.org/beaconclient/ This continues to show meteor echoes at a rate of 2 per minute or more across the day with the highest rates from 00:00 to 12:00z. Thanks to Dave Jones at the Norman Lockyer Observatory that receiver is back in operation and the faulty unit will be coming back to me for investigation and repair. Brian

GB3MBA YouTube stream 5
For the time being I have increased the displayed bandwidth to YouTube stream at https://www.youtube.com/watch?v=82S2FvYBylc to +/- 2.5KHz. This brings the timing pulses into view. These injected at the front end of the receiver to enable us to overcome latency through the receiver, the internet and the Server when we come to making detailed analysis of the echoes. With this bandwidth shown on the screen we loose some resolution of the echoes. Let me know what you think please. I will change back to +/- 500Hz later today. Brian
