Source of Chilton Ionograms

Hello All,

The Rutherford Appleton Labs ionospheric thingamybobs website seems to have been playing up for about 3 days now, and in particular, I have not been able to retrieve ionograms. I have been able to find foF2 plots here:

http://www.ips.gov.au/HF_Systems/6/8/3

But I’d really like some ionograms. Does anybody know if the Chilton ionograms are published anywhere online other than at:

http://www.ukssdc.ac.uk/cgi-bin/digisondes/latest_view2gif.pl?Station=chilton

Any thoughts appreciated.

Dave M0MYA.

In reply to M0MYA:

I’m not aware of another site that publishes the Chilton ionograms but until the RAL system is up & running again you could refer to the Belgian equivalent http://digisonde.oma.be/

Click on Public:Latest Ionogram

As Belgium is at a lower latitude I have generally found that the FoF2 is slightly higher at any particular time than it is on the RAL ionogram, but it is certainly a useful guide.

Very much so. Many thanks.

Seems to me that the Chilton site has been quite unreliable over the last few weeks. I did have a script running to periodically download them, but that has had various hiccups over the last few weeks, it seems to have stopped working completely since 12 April.

The Chilton ionogram site seems to be working again now.
