11 July - Looking promising

Strong front went through just after supper; CBs, dropped a lot of rain.  However, this morning, the temperature/dewpoint spread was 10 deg C, rather than the 4 (one day, 2) we`ve seen to date, so cloudbase should be significantly higher.  It feels nice not to have the moisture, too, in the tent.

Dr Jack and XC Skies say 3-4 kts to 4,000' by about 3 pm, and the tephigram/skew T diagrams suggest Cu will rise, then spread somewhat, worse to the north.

Tomorrow looks better yet...

KB is sniffer today.  Lift should have started at 11:00 AM, and we are about 7 OCTAS Cu, based about 3,500' right now.   It is starting to open up between the Cu.  Towplanes have been test flown.

Results for 9 July are now official and will be posted on the contest webpages later today.  The tracker has been repaired, and FAI B task is shown; the Club task is of the same geometry, but a little shorter, since the performance of the club gliders is less than the 18-20 metre FAI gliders.

Tasks take both FAI and club south-east initially, then west-south-west in the direction of Brockville, to a 'steering point' at Lodi (to avoid Ottawa airspace), then north-east (to Avocat for FAI, Montreal Soaring for Club).  These are Assigned Area Tasks, planning for 3.5 hours.  Let the Eagles dominate today!  This is the B task, initially we had them going further west, but the 1000 update to Dr Jack/XC Skies restrained the task committee a little.

FAI is first off today, then Club.  Next update when they launch.

Update - Sniffer launched at 12:30 sharp.
