Sorry folks I got it all wrong regarding yesterday's image. It wasn't noise ! Because we are only looking at +/-100Hz on the live stream I didn't recognise this as a reflection of the beacon signal from Aurora. Martin who looked at it with a wider band width sent me this image which should have been instantly recognisable as the beacon signal reflecting off Aurora. Brian

There's been a lot of meteor activity during the Eta Aquarid but today's snap is of unusual high noise level being observed at three of the receiver sites. Associated with the solar activity ? Brian PS Malvern has an indoor antenna and lower sensitivity.

Our established Receiver Live Stream is currently OFF while we move the processing to our new server and establish confidence in it. Today's screenshot is from the new server under test. Note that the frequency span displayed has been increased from +/-30Hz to +/- 100Hz . While the live display is not ideal for showing the detail of head echoes almost 100Hz of Doppler shift can be seen on the echo from the NW Hampshire H Pol receiver in this screenshot. System developments continue. Brian

Hello Folks Despite my best and very prolonged efforts we have not found a site in Scotland for our third primary receiver. Before I give up can anyone help ? What is needed is a reasonably radio quiet site with no nearby 6 m transmissions, with power, (10 W or less) and an internet connection. The data stream is about the same as an audio stream so not excessive. Ideally the site would be a minimum of 200km North of the beacon which is located near Mansfield 53.10N, 1.22W. An astronomy society with a dark sky observing site would be ideal. We would need someone local who is radio "savvy" to check the site and help with installation. A locally sourced mast of 3 or 4m would be handy but we can supply all other materials. We are trying to achieve a range of different reflection geometries for each meteor event. When we can make observations from a sufficient number of different directions it may be possible, by using Doppler measurements, to calculate the trajectory and hence radiant of the meteor. In the mean time we are working towards capturing and recording echoes from the receivers in the network together with precision timing so that events viewed from different directions can be correlated with precision. This screenshot was grabbed while typing this message. Brian

A key objective of providing the online "live" display at https://ukmeteorbeacon.org/beaconclient/ is to enable anyone with an interest in meteors and the ionosphere to make their own observations and draw their own conclusions. The images I capture and put here are just ones I happen to see when working at the computer or passing by and notice something of interest. I run a separate screen for the live displays so I don't have to stop work. Today's screenshot shows an interesting event seen at all 3 locations, Norman Lockyer, Armagh and NW Hampshire. It was particularly strong at Armagh. Note the different Doppler shifts. We are approaching the Sporadic E season. What are your thoughts on these echoes ? Brian

To: HAARP Community HAARP will be conducting a research campaign May 8-10, 2024. Attached for your reference are the campaign transmission notice and media image. The transmission notice includes supplementary information for HAARP Radio Enthusiasts and information about monitoring HAARP transmission with a software defined radio (SDR) receiver. Good luck listening, and be sure to file reception reports as described in the notice! Whit -- Whitham D. Reeve Anchorage, Alaska USA ---

This echo seen by all the operational receivers. Unusually for this time of day there have been quite a few meteor events .

This image caught yesterday shows the diversity of echo shapes we are seeing on the "live" waterfall display. The strong echo seen at the bottom of the displays was of roughly equal strength in both Horizontal and vertical polarisations at NW Hampshire and was seen faintly at Norman Lockyer but not at all by Armagh. The complex echo above it was seen quite differently from the different locations. The smaller echo seen by NW Hampshire Horizontal but not vertical was also seen faintly at Norman Lockyer but not at all by Armagh. There is so much to study. And we are still looking for a radio quiet location in Scotland for another receiver.
