Re: The new radio telescope and update at LRO
Hi, I've also purchased one of the solar cooker dishes for RA application and I saw of course you had to spray paint the mirror surface. A suggestion had been made to apply more spray paint. So how

Re: The new radio telescope and update at LRO
Looks great, and am sure it works great :-) When I get more into my Radio Astronomy journey I will look into the details more, that might be a while though :-)

FTA2 back on air?
FTA2 which is normally on 20.9kHz seemed to have come back on air at 10:02 on 6th November. However, the centre of its modulation is now on 21.04kHz. Does anyone know if this is still FTA2 with a

The new radio telescope and update at LRO
Hi All, Here is the new addition at LRO (Lichfield Radio Obaervatory, www.astronomy.network) - this radio telescope is built using a 1.5m solar cooker dish. These cost around ?50 plus postage. The

Re: muon counts
Hello John Thanks for the info.? I have only just joined the BAA and cannot yet log in ... that is being investigated.? Gamma rays, in addition to producing Muons have an effect on the ionosphere.

Re: muon counts
Hello Brian, ??? ??? You may remember from our Leicester meetings, that I write a monthly report (Radio Sky News). Originaly just covering VLF SIDs, it now includes magnetic and Muon reports.

Re: X9 Flare
I too saw the magnetic effect of this flare using a UKRAA MAgnetometer in Kent. I have been told that the sharp dip and recovery seen in the Inclination signal is called a magnetic crotchet due to its

Hi Andy, I always get a weaker signal from the transmitters behind the lower two traces so there was nothing unusual in the smaller peaks. The blue one is from Cutler, Maine and it looks as
