Ronald A. Parise, PhD, WA4SIR, passed away Friday May 9, 2008 after a very long and courageous battle with cancer. He was 57. Parise flew as a payload specialist on two space shuttle missions: STS-35 on Columbia in December 1990 and STS-67 on the Endeavour in March 1995. These two missions, ASTRO-1 and ASTRO-2 respectively, carried out ultraviolet and x-ray astronomical observations, logging more than 614 hours and 10.6 million miles in space. Parise was one of the first astronomers to operate a telescope from space, making hundreds of observations during the mission. Amateur Radio on the International Space Station (ARISS) Chairman Frank H. Bauer, KA3HDO, said Parise's personal contributions to these two missions provided scientists with "an unprecedented view of our universe, expanding our understanding of the birth, life and death of stars and galaxies."

"As the song says, 'All our bags are packed and we're ready to go' -- well, almost," said ARRL Hamvention Coordinator Katie Breen, W1KRB. "The ARRL EXPO area is packed up into seven shipping skids and they are in a truck on their way to Dayton. We here at headquarters are not only breathing a huge sigh of relief, but many of us are still wrapping up our individual final details." The Dayton Hamvention® will run from May 16-18 at Hara Arena, just outside Dayton, Ohio.

Again this week, we saw a new, but brief sunspot, sunspot 993. Judging from the polarity of the spot, it looks to be from new Solar Cycle 24; this spot was south of the solar equator, so it has the same polarity as any Cycle 23 spot that was north of the equator. After two days it was gone, not from drifting over the edge of the visible solar disk -- it just disappeared.

AT 11 AM...THE HEAVIEST RAIN WAS ACROSS NORTH CENTRAL
MARYLAND...MOVING NORTHEAST ALONG THE PENNSYLVANIA BORDER. A
QUARTER TO HALF INCH OF RAIN ALONG THIS TRACK. FURTHER SOUTH
ACROSS THE BALTIMORE AND WASHINGTON METRO AREAS AND THE INTERSTATE
66 CORRIDOR...LIGHTER PRECIPITATION UP TO A TENTH OF AN INCH IS
EXPECTED DURING THE EARLY AFTERNOON.

A COLD FRONT WILL CONTINUE TO SETTLE SOUTH FROM ANNAPOLIS...WASHINGTON
DC...AND WINCHESTER THIS AFTERNOON. NORTHERLY WIND GUSTS OF 20 TO
30 MPH WILL BRING COOLING TEMPERATURES BEHIND THE FRONT THIS AFTERNOON.
