It was quite a busy weekend for our Sun. During the late hours of Friday, July 30, a magnificent coronal mass ejection (CME) billowed away from the eastern limb of the Sun; the source of the blast was apparently sunspot 1092. On Sunday, August 1 at approximately 0855 UTC, Earth-orbiting satellites detected a C3-class solar flare, and again, the blast came from sunspot 1092. At about the same time as the solar flare, an enormous magnetic filament erupted, stretching across the Sun’s northern hemisphere, a complex global eruption involving almost the entire Earth-facing side of the Sun.

This week's bulletin was made possible with information provided by
DS4GGM, NC1L, The Daily DX, QRZ DX, the OPDX Bulletin, DXNL, Contest
Corral from QST and the ARRL Contest Calendar and WA7BNM web sites.
Thanks to all.

Further to recent reports on GB2RS we are delighted to confirm that the author of ROS has definitely decided to continue development work. The software's author, Jose Alberto Nieto Ros, told GB2RS that he will be implementing new modes and enhanced facilities. The most recent development is an auto reporting system linked into the PSK-Reporter system at http://pskreporter.info/pskmap.html. The latest version of ROS is available for download at http://rosmodem.wordpress.com.

A new world record in distance on 10GHz has been established between the Cape Verde islands and southern Portugal. On 10 July at 10:46 UTC the previous record of 2070km was smashed by a SSB QSO at 2696km during the Hyperatlantica 2010 DXpedition. A detailed report will appear in the September 2010 RadCom but in the meantime details, in French, can be found at www.hyperatlantica.ch. Congratulations to all involved.

Sunspot activity increased recently, although it is foolish to call
this a trend because solar activity has great variability. Sunspot
group 1087 was visible for 13 days over July 9-21. In millionths of
a solar hemisphere, its size was 30, 100, 120, 130, 70, 100, 60, 50,
20, 10, 10, 10, and 10. On July 19 new sunspot group 1089 appeared
over the eastern horizon, with a relative size of 130, 150, 310 and
240 for July 19-22.

David Warren, who is widely credited with creating the prototype of the flight data recorder, or “black box,” an advance in aviation that was partly inspired by the death of his father in a plane crash when he was 8, died on Monday in Australia. He was 85.

David Warren, whose father died in an air disaster, is credited with creating the flight data recorder. He made no profit from it.
His death, at a nursing home in Brighton, a suburb of Melbourne, was announced by Australia’s Defense Department.

Mr. Warren, a government aeronautical researcher who had operated a ham radio as a boy, worked against skepticism and ridicule to create his device. But it, and later generations of it, proved to do exactly what he thought it would: simultaneously record the conversations of pilots and instrument readings.

Two new sunspot groups appeared in the last week, groups 1087 and
1088. 1088 lasted just one day, on July 13, 2010 with a relative
area of 10 (millionths of a solar hemisphere). Sunspot group 1087
had a relative area from July 9-15 of 30, 100, 120, 130, 70, 100 and
60.
