KA6BQF requests help for a 20 Mile Boy Scout Hike on June 3, 2017.

Randy Jenkins, KA6BQF is looking for help with the FAGES II Boy Scout Hike on June 3rd. The Boy Scout event starts and finishes at Camp Herms in the Berkeley Hills; and goes over trails in Wildcat Canyon and Tilden Regional Parks. Between 50 and 200 Scouts and adult leaders participate. Randy needs 8 to 12 Hams to man staff check points along the trail, and check in and report participants by Troop. Early checkpoints are shorter duration. Net control is at the lunch stop until all participants have cleared that point, and transfers to the checkout point for the final participants. Hams may volunteer as radio equipped sweeps.

Cal Balloon Launch details of March 18, 2017 Flight

Reported by Randy Jenkins KA6BQF

ka6bqf@gmail.com

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.  The balloon reached an altitude of 108.346 feet, and traveled from the Berkeley campus to west of Folsom, CA. When the balloon passed through the cloud deck, the APRS data showed a velocity in excess of 100 mph.  The chase team kept in touch, via amateur radio.  The balloon team included UC staff and students including K6JEB, W6MMR, and KJ6DBZ.

The balloon was named Henry-1, after the late UC Space Scientist Henry Primbsch, KK6PH.   There will be a story with more details on the EBARC page.  http://www.ebarc.org/hab.htm    The team played the recovered video from the cameras at the March EBARC meeting.

Grizzly Peak Century bike ride May 7th

Randy Jenkins, KA6BQF is looking for help with the Grizzly Peak Century Ride on May 7th. The event is a 60 and 100 mile bicycle ride involving around 700 cyclists, on paved roads, through the East Bay hills. Start / Finish is in Moraga. Course runs north as far as Port Costa and south as far as Castro Valley. Amateur radio operators provide communications between six fixed location rest stops. Some hams also volunteer as sag drivers or sag communicators. Randy needs 9 to 12 operators for fixed locations, 5 to 11 sag drivers or communicators.

The International Cloud Atlas has been added as a Link

Welcome to the official site of the World Meteorological Organization’s (WMO) International Cloud Atlas. This Atlas describes the classification system for clouds and meteorological phenomena used by all WMO Members. The classifications also describe meteorological meteors other than clouds – hydrometeors, lithometeors, photometeors, and electrometeors.

The Atlas provides a common language to communicate cloud observations, and ensures consistency in reporting by observers around the world. It serves as a training tool for meteorologists, as well as for those working in aeronautical and maritime environments, and it has become popular with weather enthusiasts and cloud spotters.

6 Year Anniversary of the Japan Tsunami of March 11, 2011 You Tube Video

A few years ago I had the pleasure of visiting Japan and met some great people.  I found they share one of the same concerns those of use who live California have…the ever present chance of an earthquake.  On March 11, 2011 they had a magnitude 9 earthquake that shook northeastern Japan and unleashed a massive tsunami.  In researching the catastrophe that followed I came across a You Tube video that shows how the tsunami unfolded in real time in a city called Kesennuma located in northeastern Miyagi prefecture, northern Honshu, Japan.

The below two Google Earth photos is a close up of the Kesennuma School area before and after tsunami.

When you examine the above 2 pictures you may want to go to Google Earth and look in greater detail at the surrounding area.  The images are startling.  It is worth looking at other Google Earth photos of the same area since it shows how slow recovery can be…

The videographer was near the Kesennuma School when it all began and did an amazing job of capturing the tsunami as it unfolded.  To view the amazing 26 minute video click below…
