This method of entry requires no money, just a little of your time. Make sure to leave your phone number or e-mail address so we can contact you if you win. Your personal information will not be disclosed, but your response will be played on the air!
- You can render artistically in some way your concept of a Raspberry Pi. This can mean the computer, a raspberry pie, or some other interpretation we haven’t thought of yet. You can use any artistic medium, from a sketch to beat poetry. Be creative! You will receive TWO entries into the contest if you choose this option. We will post your creativity on the Web site for others to enjoy, and mention what you’ve done on the show. Have fun with it!

An Amazing Moment in Space Weather – Massive Solar Eruption June 2011
While many are talking about how Solar Cycle 24 is the weakest since the Maunder Minimum (the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time — see this Wiki entry), there are moments when activity on the Sun strongly increases, providing brief moments of excitement.
Here is a case in point, witnessed by the Solar Dynamics Observatory (SDO; see SDO Mission) on June 7, 2011, when the Sun unleashed a magnitude M2 (a medium-sized) solar flare with a spectacular coronal mass ejection (CME). The large cloud of particles mushroomed up and fell back down looking as if it covered an area almost half the solar surface.
SDO observed the flare’s peak at 1:41 AM ET. SDO recorded these images in extreme ultraviolet light that show a very large eruption of cool gas. It is somewhat unique because at many places in the eruption there seems to be even cooler material — at temperatures less than 80,000 K.
This video uses the full-resolution 4096 x 4096 pixel images at a one minute time cadence to provide the highest quality, finest detail version possible. The color is artificial, as the actual images are capturing Extreme Ultraviolet light.
It is interesting to compare the event in different wavelengths because they each see different temperatures of plasma.
