A KiwiSDR Dynamic SNR Map

Many thanks to SWLing Post contributor, Mark Fahey, who shares the following comment in response to our KiwiSDR post from yesterday:

[T]here are now so many [KiwiSDR] receivers – how do you know which ones are best? Why not use this map as an alternative to sdr.hu/map:

[A]ll the same receivers are shown in a map interface but the receiver signal to noise ratio changes how big each receiver target appears. The bigger the blob, the better the lower the noise which usually equates to a better antenna system etc.

Wow!  Thanks for the excellent tip, Mark! This map makes exploring the KiwiSDR network much easier. I especially like the full screen option.

Note, too, that Mark hosts a KiwiSDR in Freemans Reach, Australia (near Sydney). Mark sets the default auto logout for 2 hours to better cater to SWLs (which he says only represents about 10% of his SDR guests!). Most KiwiSDRs use the 30 minute default auto logout, which I find frustrating when I’m making broadcast recordings.

G-1 Geomagnetic Storm, Chance of a G-2 Storm 11-12 Sep

From Spaceweather.com:

“NOAA forecasters say there is an 80% chance of minor G1-class geomagnetic storms on Sept. 11th when a stream of solar wind is expected to hit Earth’s magnetic field … There’s a chance that the storm could intensify to category G2 (moderately strong).”

Will this impact your radio plans over the next two days?  Go to Spaceweather.com for updates.

UPDATED 10:30 P.M. EDT:

I just received this update from the Forecast Center:

Product: 3-Day Forecast
Issued: 2018 Sep 11 0030 UTC
Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction
Center

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 5 (NOAA Scale
G1).
The greatest expected 3 hr Kp for Sep 11-Sep 13 2018 is 6 (NOAA Scale
G2).

NOAA Kp index breakdown Sep 11-Sep 13 2018

            Sep 11     Sep 12     Sep 13
00-03UT        5 (G1)     4          3     
03-06UT        6 (G2)     5 (G1)     4     
06-09UT        5 (G1)     4          3     
09-12UT        4          3          2

21-00UT        4          2          2     

Rationale: The geomagnetic field will likely reach G2 (Moderate) levels
on day one( 11 Sep) as a result of a positive polarity CH HSS. Activity
is expected to taper some by day two (12 Sep), but G1 (Minor) storm
conditions are still likely. Day three (13 Sep) is expected to be a day
of transition, with G1 conditions becoming less likely.
