ARLP015 Propagation de K7RA
No sunspots were seen over the past reporting week, April 5-11, so
average daily sunspot number declined from 3.3 to 0. Average daily
solar flux declined from 68.6 to 67.7. Average daily planetary A
index increased from 5 to 9.4, and average daily mid-latitude A
index went from 4 to 8.1.
But on Thursday, April 12, a new sunspot appeared, AR2704, and it is
a small one. However this one is three times the size of new sunspot
groups appearing on March 30, March 17, March 15, and March 2.
Spaceweather.com reported:
"A minor G1-class geomagnetic storm is in progress on April 11th as
Earth moves through a high speed stream of solar wind.

Зачем строить собственные радиостанции, если сегодня в любой момент можно связаться по телефону или по интернету с любой точкой Земли?
Зачем люди надевают тяжелый рюкзак и целый месяц идут пешком туда, куда можно за час долететь на самолете? Зачем встают в четыре часа утра и весь день сидят с удочкой на берегу реки, если можно купить сколько угодно рыбы в ближайшем магазине? - потому что это им интересно, потому что они получают удовольствие не только от результата, но и от процесса.
В нашем случае - это и процесс познания, и процесс технического творчества, и спортивный азарт, и увлеченность коллекционера.
С любой точкой Земли связаться по интернету или телефону, на самом деле, пока еще далеко не всегда возможно. Но если там есть радиолюбитель - то можно наверняка.
