Solar flare produces radio shock wave
A solar flare from an emerging sunspot Monday, November 6, between 1740 and 1748 UTC, produced a
fast-moving radio shock wave. "It sounded like a freight train," says Thomas Ashcraft, who recorded the
burst at his radio observatory in New Mexico and maintains a Web site on audible solar phenomena.
Ashcraft says the C8.8 solar X-ray flare caused a moderate-to-strong -- and especially fast -- Type II radio
burst event, traveling from the sun at 2230 km per second! His stereo recording of the November 6 event
provides solar radio noise on 18.7 MHz in one channel and on 22.2 MHz in the other (headphones highly
recommended). SpaceWeather.com reports the sunspot, hidden just behind the sun's eastern limb, is
erupting and hurling clouds of magnetized gas high above the solar surface.
Moonbounce experiment 'Project Diana' commemorated
The Ocean Monmouth Amateur Radio Club in the US will put special event callsign N2MO on the air on
14 to 15 January next year to commemorate the first successful moonbounce experiment. This was carried
out by the US Army Signal Corps on 10 January 1946 in what was known as Project Diana. The special event
station will be activated from the historic Project Diana site at the InfoAge Learning Centre in New Jersey.
Ocean Monmouth ARC plans to operate the special event station using ALE, CW, PKS31, RTTY and SSB on
the 80, 40, 20, 15 and 10m bands. You can find out more about Project Diana on the web at www.omarc.org
Also refer to the article on Project Diana in the May 1946 edition of QST magazine.

The group will also take suggestions for the normal weeklong operational periods as well. Every member of the Operations Group will receive emails from this address. This is your chance, the amateur satellite user, to request from the AO-51 Operations Group the modes you are interested in seeing operated on the satellite during the weekly Wednesday sessions. Do not expect a reply to every email, as there will not be time to respond to each one, but your input will be noted. The email address to send your requests or ideas to the Operations Group is: ao51-modes@amsat.org The AO-51 Operations Group is made up of AMSAT members who are also AO-51 users. The Operations Group works with the Command Team to create the monthly schedule for the satellite. 73 KO4MA For AO-51 Operations Group (KO4MA, WD9EWK/VA7EWK, N8MH, OZ1MY, VK5HI, KE4AZN, WA4SXM) |
