Valentine's Day Submission

Here's a heart-shaped active region observed by the X-Ray Telescope aboard Hinode that could be great for the Valentine's Day picture:

Here is the view seen by the X-Ray Telescope aboard Hinode, whose orbit passed through the moon's shadow twice for this event. Visit our main site for more information, and be sure to set the resolution to 720p if your connection will allow!

Howdy Asternauts, It's been a while since I've posted anything to your wonderful forum, so I've been waiting for something particularly striking to return with. I hope you enjoy this movie of full-sun x-ray observations over the last five and a half years! The images were taken by the X-Ray Telescop...

Today we have a set of three videos all showing different aspects of solar flares and coronal mass ejections. The first shows a particularly "flare productive" active region as it evolves over 4 days. In the left panel, a thinner filter combination is overexposed to show extended structure...

Here are 4 videos just uploaded to YouTube. Enjoy! Head over to the actual YouTube pages for descriptions.

Hurray Asternauts, XRT did indeed see Comet Lovejoy! The detection was *extremely* faint, and if you follow this link to our original post , you'll be able to see why I had a hard time realizing that we'd seen it all. I'm sure you're all up on Lovejoy's story, so I'll skip that and just mention that...

It took me a week or so to recover from the disappointment of not seeing any trace of Comet Lovejoy in XRT data, but now we're back with another installment: Today's movie shows NOAA Active Region 11374 as it develops over about a day and a half from Dec 11-13. In the left panel we have images taken...

A new-to-YouTube movie for your enjoyment. Tune in Friday for any XRT data capturing the effects of Comet Lovejoy ; we're not sure, but hopefully we see something... *fingers crossed* On 2011/10/31, XRT observed an unusual series of jets from NOAA active region 11330 . One of the early results from ...

Today's movie attempts to follow a fixed location on the sun as it comes back around after each rotation period. Each frame advances time by one Carrington rotation period, around 27.3 days. Following one spot on the sun is a tricky endeavor because the sun is not a solid body and is therefore subje...

Hello Everyone! I'm excited to join the asternauts here to share some videos produced by the XRT team . XRT (X-Ray Telescope) is one of three instruments aboard the Japanese satellite Solar-B, or Hinode (sunrise). Hinode launched in September of 2006 and has been sending back wonderful new and scien...
