Latest SWPC 3-day Space Weather Forecast

Latest SWPC 3-day Space Weather Forecast: Geophysical Activity Forecast: The geomagnetic field is expected to begin the forecast period at mostly quiet levels until the arrival of the 20 Nov CME midday on day one (23 Nov) when conditions are expected to rise to active levels with a chance for minor storm periods. Conditions have a chance for reaching major storm levels early on day two (24 Nov) with the expected arrival of the 21 Nov CME. On day three (25 Nov) conditions are expected to return to unsettled to active levels due to CME combined with high speed stream effects.

10m WSPR spots @ G4ILO 17 November 2012

Another day of good propagation. I don’t know why OH1CO was using the suffix /QRP (aren’t most WSPRers using 5w or less?) but it really upset the WSPR encoding algorithm. His call was being decoded at my end as OH1/P00XEK!

It’s magic!

I’m starting to believe that my attic dipole does have magical powers on 10 metres. Right now I’m hearing or being heard by 8 different stations but they are only hearing or being heard by me!

10m WSPR spots @ G4ILO 16 November 2012

Poor conditions

Propagation is really poor at the moment. Never has my WebProp propagation widget been quite so accurate. On 10m WSPR I am hearing nothing and no-one is hearing me. On 30m APRS it’s just as bad. I’m not picking up a single packet.

I opened WebProp’s page in Google Chrome and noticed that the small format widget had a vertical scrollbar on the right hand side. I thought I could remove it by adding a few pixels to the iframe height attribute but it didn’t seem to make any difference. I think a bug in Chrome might be causing this. The presence of the scrollbar reduces the width of the table causing several lines to wrap and making the table taller.

I found that the scrollbar was eliminated by adding the attribute scrolling=”no” to the iframe definition. If you are using WebProp on your website I recommend you do the same. If you aren’t sure exactly what to do then go to the WebProp web page. The code examples have all been updated with this extra attribute.

I recommend you to do this even if you don’t see the scrollbar in Google Chrome. That will prevent it from appearing in any web browser.

10m WSPR spots @ G4ILO 13 November 2012

Some pretty good propagation on 10m today, though not exceptional. During the morning it was interesting to note several spots of G and GW stations. I was received by fellow blogger Tim G4VXE. I didn’t hear him though.

I took time out to make a few digital contacts. I worked two Russians on 12m (using the 10m dipole) then a few more plus a couple of Americans on 10m. Best contact was NP3IR Hector in Puerto Rico, who has just this minute spotted me on WSPR too!

That’s cool! I can mark and copy lines from my contact log, then paste them into Blogger and they come out formatted. Never knew you could do that.
