| I may not be able to participate in the experiment, but it occurs to me that report from outside the area expected to be affected might also be useful.

Thanks Andy
Thinking aloud , you may be too far south for the TF3 path on 477 , Finbar EI0CF will be sending on 477 , [Ideally placed ] , I intend to TX also on 477 ,
Hopefully on the 1000 mile arc from TH3 , 477 tx stations from PA - LA - SM zones would be ideal ...
That puts your location , best placed for the 200/300 Miles shorter southern skip ?
There is no central control as such for Opera , but the 3 band Rx would perhaps be the most valuable option ?
Noting, Top band being perhaps the next in line interims of measurable effect , that would provide the Russian Top band users, a well placed monitoring point as well as any more local activity from Uk or EU etc
If you take that option Andy , that covers the 477 band North TH3HZ and South Rx, yourself, quite well , additional Rx stations in the shorter ranges would complete the monitoring requirements ?
Thanks

Hello Graham.
I want to participate to the OPERA test during the morning of Friday 20 March 0800z to 1200z.
But I have 2 choices. Please tell me what is the best one for you ?
1. I can transmit, but only one one band, 630, 160 or 80 meters ;
2. Or, I can receive on the 3 bands at the same time. After the event, I’ll send all the OPERA reports by Internet using any file format (txt, xls, pdf.....).
I hope that many stations be active for this event.
Best 73.

Partial solar eclipse propagation experiment, March 20th 2015
Call for Opera users
There is a unique opportunity to participate in gathering propagation data during a solar eclipse, occurring, during the morning of Friday 20 March 0800z to 1200z.
The Opera system is well suited to the requirements and in liaison with the RSGB project coordinator , Steve G0KYA , Opera mode is added to the list of experiments.
User participation: A change from the normal
Its requested MF and 160 participating stations , elect to be either Tx or Rx only ,
Due to the short length of the event, round 4 hours, to maximise the quantity and quality the of data produced from the 477KHz and 1.8 MHz bands,
Tx Stations are requested to send at 100% no beacon timer and no CW i/d,
Rx Stations are requested to maintain ‘Fixed band’ watch over the time window.
[Rx Stations , Copy and paste the local decode results to text file as back up to the PSK-Map data base]
Three sections of the spectrum are of particular interest:-
MF 477 KHz / OP8 Tx @ 100% No CW ID
HF 1.8MHz / OP4 , Tx @ 100% No CW ID
HF 3.5 MHz / OP2 , 7 MHz / OP2 Normal operations
One of the main areas of interest is the North / South path straggling the line of Totality, this being roughly central to a 1000 mile path from the UK/EU to Iceland.
MF: 477KHz ‘Totality Path’: Halldor TF3HZ has undertaken to establish a web-linked Rx monitor for 477KHz OP8 and will set up in the week previous to the event.
MF: 477KHz Inter ‘UK / EU’: Stations are also invited to join the experiment , noting , Tx / Rx stations are requested to follow the 100% Tx and Rx continuous availability.
HF Bands
Opera is one of many systems to be deployed during the event on HF .
1.8 OP4 Operations requested to follow the MF 477 KHz format
3.5 and 7 MHz bands , deploying OP2 mode , normal operations
