BIG TWISTER
Movies: Quicktime Large (26MB), Small (4MB); MPEG Small (7MB)
The time-lapse movie spans three days, April 30th to May 2nd, and shows not only the big twister, but also many smaller filaments that twist and swirl without erupting. Such activity occurs every day and is part of the dynamism of the ever-changing sun.
More great movies from STEREO may be found here.

New Kenwood Rigs.
Website: http://www.kenwood.co.jp/en/news/2010/20100507.html
Launch of New Amateur Radio Products:
Kanagawa, Japan, May 7, 2010 — Kenwood Corporation, an operating company of the JVC Kenwood Group, is proud to announce the autumn/winter launch of two new Amateur Radio transceivers: the TS-590S and TH-D72.
HF/50MHz All-Mode Transceiver - TS-590S (tentative naming)
Featuring a 32-bit floating-point DSP, the TS-590S will offer advanced receiver performance and an extensive range of features that make it ideal for beginner and seasoned DX’er alike. The radio’s exceptional ease of operation, true to the Kenwood tradition, will be especially welcome for contest and mobile applications.
144/430MHz Dual Band FM Portable - TH-D72 (tentative naming)
The APRS® capability found on Kenwood’s TH-D7* and TM-D710 has been upgraded for the TH-D72. Thanks also to the internal GPS unit, APRS operations will be more enjoyable than ever. The TH-D72 also offers EchoLink® memory compatibility and a mini-USB connector for enhanced computer connectivity. This transceiver is sure to make ham radio operations easier and more fun for all.
* For overseas model/Discontinued model
Anyone interested in these two models will be able to view product samples at: Dayton Hamvention 2010 (Dayton, Ohio, USA, May 14-16), and HAM RADIO 2010 (Friedrichshafen, Germany, June 25-27).
Please note that as these products are under development features and specifications are subject to change without notice.

National Day of Prayer
History of the National Day of Prayer
1775 The First Continental Congress called for a National Day of Prayer.
1863 Abraham Lincoln called for such a day.
1952 Congress established NDP as an annual event by a joint resolution, signed into law by President Truman.
1988 The law was amended and signed by President Reagan, to be the first Thursday in May.
2010 U.S. District Judge Barbara B. Crabb ruled that the National Day of Prayer is "unconstitutional."

Monday Humor
A woman was standing nude, looking in the bedroom mirror. She was not happy with what she saw and said to her husband, "I feel horrible; I look old, fat and ugly. I really need you to pay me a compliment.' The husband replied, 'Your eyesight's perfect.'
HOW TO READ PROPAGATION NUMBERS
The A index [ LOW is GOOD ]
- 1 to 6 is BEST
- 7 to 9 is OK
- 11 or more is BAD
Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.
A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
SFI index [ HIGH is GOOD ]
- 70 NOT GOOD
- 80 GOOD
- 90 BETTER
- 100+ BEST
The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.
Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.
K index [ LOW is GOOD ]
- 0 or 1 is BEST
- 2 is OK
- 3 or more is BAD
- 5 is VERY VERY BAD
The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.
A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
