Data for solar radio bursts can also be obtained from the following international sites (east to west):

Culgoora and Learmonth, Australia: Dynamic spectra from 18 to 1800 MHz. The two sites are operated by the Ionospheric Prediction Service Radio and Space Services division of the Australian Governement: the historic site at Culgoora in northern New South Wales (longitude 149 east, latitude 30 south) where the radioheliograph once operated and the Australia Telescope now sits; and the observatory at Learmonth on the northern coast of Western Australia (longitude 114 east, latitude 22 south), jointly operated with the US Air Force who have a radio patrol system there. Click on the "Spectrographs" link for Culgoora or Learmonth to see current data, click on "Historical" to see older data.

BIRS, Bruny Island, Tasmania Dynamic spectra from 5 to 65 MHz. Operated by Bill Erickson in his back yard, BIRS takes advantage of the low ionospheric cutoff frequency over Tasmania to observe bursts down to 10 MHz or below. Longitude 147 east, latitude 43 south. Recent data may currently also be found on this web site.

Nobeyama, Japan: Single frequency light curves at 1, 2, 3.8, 9.4, 17, 35 and 80 GHz in addition to radioheliograph imaging data at 17 and 34 GHz. Operated by the National Astronomical Observatory of Japan at longitude 138 east, latitude 36 north.

Hiraiso, Japan: Dynamic spectra from 25 to 2500 MHz and single-frequency light curves at 200, 500 and 2800 MHz. Operated by the National Institute of Information and Communications Technology, Japan, and located at about longitude 136 east, latitude 35 north.

Izmiran, Russia: Dynamic spectra from 25 to 270 MHz and single-frequency data at 169, 204, and 3000 MHz. Located in the Moscow region at longitude 35 east, latitude 56 north, and operated by Izmiran, the Institute of Terrestrial Magnetism, Ionosphere and Radiowave Propagation of the Russian Academy of Sciences.

Cracow, Poland: Single-frequency light curves at 275, 405, 670, 810, 925, 1080, 1215, 1350, 1620, 1755 MHz. The observations are performed by the Astronomical Observatory (founded 1792) of the Jagiellonian University (founded 1364) with an 8m antenna at longitude 19 east, latitude 50 north.

Ondrejov, Czech Republic: Dynamic spectra from 800 to 4500 MHz, single-frequency light curve at 3000 MHz. Operated by the Astronomical Institute of the Academy of Sciences of the Czech Republic at longitude 14 east, latitude 50 north.

Trieste, Italy: Single-frequency observations at 237, 327, 408, 610, 1420, and 2695 MHz. Operated by the Italian Instituto Nazionale di Astrofisica (INAF) at longitude 14 east, latitude 45 north.

Tremsdorf, Germany: Dynamic spectra from 40 to 800 MHz. Located at longitude 13 east, latitude 52 north, and operated by the Astrophysikalisches Institut Postdam of the German state Brandenburg. When operating, real-time data can be found here (previously here).

Bleien, Switzerland: Dynamic spectra from 50 to 850 MHz (Callisto spectrometer) and 100 to 4000 MHz (Phoenix-2). Operated by the Institute of Astronomy at the Eidgenossische Technische Hochschule (ETH), Zurich. Bleien is at longitude 8 east, latitude 47 north.

Meudon SECCHI-RH: New web site with a compilation of radio data from a number of sources, including Nancay, ARTEMIS and WIND/WAVES, together with coronal data from the SOHO and STEREO missions.

Nancay, France: Radio flux measurements between 150 and 450 MHz in addition to radioheliograph imaging data at 5 frequencies. Operated by the Observatoire de Paris and funded by the French research agency CNRS; located at longitude 2 degrees east, latitude 47 north. Sample images and daily dynamic spectra in the range 20-70 MHz may be found at the BASS-2000 web page.

GDRT, USA: Daily data page gives access to data collected by the NASA/GSFC radio group, including the Ulysses RAP data, the Goddard Decametric Radio Telescope (GDRT) , another low--frequency spectrometer based on BIRS, operating from 5 to 62 MHz and located at the Goddard facility in Maryland, on the edge of Washington DC. Use the pull-down menu at the top of the page to select the data desired. Longitude 77 west, latitude 39 north.

SRBL, USA: Dynamic spectra from 1 to 18 GHz. Operated by the New Jersey Institute of Technology at the Owens Valley Observatory of Caltech, longitude 118 west, latitude 37 north.

OVSA, USA: Interferometer imaging data and flux measurements from 1 to 18 GHz. Operated by the New Jersey Institute of Technology at the Owens Valley Observatory of Caltech, longitude 118 west, latitude 37 north.

US Air Force RSTN data: Dynamic spectra from 25 to 180 MHz and single-frequency microwave data at 0.2, 0.4, 1.4, 2.7, 5.0, 8.8, and 15 GHz are obtained at the Radio Solar Telescope Network (RSTN) observatories operated by the US Air Force in Sagamore Hill (MA, longitude 71 east, latitude 42 north), Holloman AFB (NM, longitude 106 west, latitude 33 north), Palehua (Oahu, HI, longitude 158 west, latitude 21 north), Learmonth (Australia, longitude 114 east, latitude 22 south) and San Vito (Brindisi, Italy, longitude 18 east, latitude 41 north). Recent data are available (with delays of several months) from NASA's NGDC site: the dynamic spectra are in the SPECTRAL_RSTN directory under monthly subdirectories labelled by observatory (HOLL, LEAR, PALE, SVTO; only some recent data are available from Sagamore Hill/SGMR) and month (yymm). The data are in SRS format and can be viewed in the Windows operating system using a standalone viewer SRSDisp.exe supplied by the Australian IPS service and described in a Word document. There are now IDL routines to read and plot dynamic radio spectra of solar radio bursts from the Air Force RSTN network of patrol telescopes in the NGDC package of Solarsoft that are versions of my original routines, and, improved by Sam Freeland (the Solarsoft versions use UNIX sockets instead of wget) and made compatible with Solarsoft practices. The routine will download data from NGDC but it is best for you to check first that data are available. Single-frequency data are in ASCII files under the RSTN_Radio_Solar_Telescope_Network_1second_data subdirectory.
