SPACE WEATHER WOMAN

There Goes the Sun


Dear <<First Name>>,

It's a sad day when our Sun gets eclipsed by other Space Weather events. In this case I'm joking of course, but there is a hint of truth to my statement. This week, both a meteor explosion and our moon are the "stars" of the show. The meteor, which exploded in the skies about 300 km south of Puerto Rico on June 22, was determined to be equivalent to a 5 kiloton detonation. Continued analysis of its northwest track across the Caribbean Sea indicates that if it had been larger (or our atmosphere thinner) it could have impacted any of the Caribbean islands or even crashed down into Mexico.

This week the moon also eclipses the Sun because, well, it literally will eclipse the Sun on July 2. This total solar eclipse will be visible only in the south Pacific and across South America. However, it will be well observed and streamed online by many with solar telescopes. Quite a few of my Space Weather colleagues plan to be among those travelling to Chile and Argentina for the show. Total solar eclipses give us scientists the rare chance to study the fine details of the solar corona using instruments only found on the ground. This is such a big deal that some of my colleagues have even created predictions of what the Sun's corona will look like with the naked eye during totality. I'm thrilled to be able to share these predictions with you in this week's forecast.

As for the weather from our star this week, its definitely quiet. Emergency and amateur radio responders got a serious dose of this quiet during "Field Day" last weekend. I've gotten many reports of poor radio propagation, especially on Earth's dayside. Things should improve slightly this week, but that is little consolation. The picture above is a snapshot during my mandolin duet with Ward Silver (N0AX) at Contest University last month. We were parodying the famous Beatles tune "Here Comes the Sun." This panoramic shot also shows the lyrics we were singing at the time (see the left side of the photo). Not to be too tongue-in-cheek, but I think that pretty much says it all.

Cheers,
Tamitha
