The Sun Emits an M5.9 Solar Flare



www.nasa.gov said:

The sun emitted a mid-level solar flare, peaking at 6:49 p.m. on June 7, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours.

I assume that this flare was earth-bound due to the R2 rating. I've noticed from other reported CME phemonena that sometimes the mass ejection can be directed towards Mercury for example. I wonder why this wasn't explicitly mentioned in the NASA article?

The object, known by the locals as "Bicho Voador" (Flying Animal), or "Bicho Sugador" (Sucking Animal), has the shape of a rounded ship and attacks people in isolation.

The rating has nothing to do with whether they are Earth pointing or not, it just denotes the intensity of the flare.

Why should it be?

Most flares are not pointed at any planet. NASA tend to mention if it is pointed at Earth, a planet or towards operational space probes. As they did not mention any of these things it is likely that none of them were affected by this particular flare.
