Balloon launch Flier<\/a><\/p>\n

On Saturday, March 18, a high-altitude research balloon was launched from the UC Berkeley campus carrying amateur radio equipment, including APRS, using the call sign W6BB-1 and a cross-band repeater, and other experiments.<\/span>\u00a0 <\/span>The balloon reached an altitude of 108.346 feet, and traveled from the Berkeley campus to Folsom, CA. When the balloon passed through the cloud deck, the APRS data showed a velocity in excess of 100 mph. <\/span>\u00a0<\/span>The chase team kept in touch, via amateur radio.<\/span>\u00a0 <\/span>The balloon team included UC staff and students including K6JEB, W6MMR, and KJ6DBZ.<\/span><\/p>\n

The balloon was named Henry-1, after the late UC Space Scientist Henry Primbsch, KK6PH.<\/span>\u00a0\u00a0 <\/span>There will be a story with pictures and\u00a0more details on the EBARC page: <\/span>\u00a0http:\/\/www.ebarc.org\/hab.htm <\/a><\/span>\u00a0\u00a0\u00a0 <\/span>The team played the recovered video from the cameras at the March EBARC meeting.<\/span><\/p>\n
