Self-Updating Movies are Having Troubles

The Kiosk, or Self-Updating, movies no longer work if started from a .html file on a machine other than the SDO server. They do work if they are started from the SDO website (such as by clicking the link at http://sdo.gsfc.nasa.gov/data/kiosk.php.

This is related to a website security update. Frames from outside the sdo.gsfc.nasa.gov domain can't initiate an iframe without having that specific website on a whitelist. We are working to deliver the same functionality without having to maintain that whitelist.

Until then, please use the three examples on the kiosk webpage.

Happy π Day!

100,000,000 Images from HMI!

Here is the 100,000,000th image seen by HMI! It was snapped yesterday (March 8) at 0453 UTC (11:53 pm ET on March 7). Unlike the 100,000,000th AIA image we talked about last year, most people don't look at the individual HMI images. HMI images are processed and manipulated to make Dopplergrams and magnetograms.

My congratulations to the Stanford and LMSAL team that built and now run the HMI instrument. The Dopplergrams, magnetograms, and intensitygrams that we see everyday are the result of their excellent work. They are used by space weather forecasters around the world to track what the Sun is doing. The Dopplergrams have been used to look at how material moves around deep inside the Sun's convection zone.

Another 100,000,000 HMI images please!

A Station Keeping Maneuver in the Spring 2016 Eclipse Season

SDO's Spring 2016 Eclipse Season started on February 19, 2016, with the Earth passing between SDO and the Sun at 0712 UTC that day. The top picture shows the Earth moving across the Sun in an AIA 171 Å image while the bottom picture shows the Earth almost covering the Sun 15 minutes later. Eclipse season runs through March 12, 2016.

On Wednesday, March 2, 2016, SDO will execute stationkeeping maneuver #12 at 2250 UTC (5:50 p.m. ET). Science data will be unavailable for about 45 minutes starting 2235 UTC. These maneuvers are used to help SDO be a good neighbor in the geostationary belt that we pass though twice each day.

Happy Launch Anniversary SDO!

Today is the 6th anniversary of the SDO launch. I was looking for a good picture or movie when this came in my email. It says it all.

Happy Birthday SDO. What a great mission.

January Maneuvers

Last Wednesday SDO did the HMI/AIA roll maneuver, where the satellite spins around to help the scientists better understand the instruments. Here's an example of an image during the roll at 1523 UTC. With the south pole on the left, the filaments look a little like a cat or harlequin!

This afternoon SDO will do the EVE cruciform, moving in a plus sign figure to measure how light reflects inside the instrument. From 1800-2300 UTC (1:00-6:00 pm ET) the Sun will appear to move around and be blurry. Enjoy!

Short Outages in the SDO Website and Data Flow

Since Monday there have been several interruptions in the SDO website and data flow. On Monday a test of the Inertial Reference Units resulted in SDO pointing slightly off center for about 90 minutes. Some data may not be created during that time. On Monday and Tuesday our system administrators were updating the SDO website and, perhaps in anticipation of their impending replacement, one of the older RAIDs failed. There have been several interruptions as the SAs repair the issues and these will continue this week. SDO data continues to flow to the data centers.

2015 was a Very Good Year

2015 was a great year for SDO! We finished our prime mission and began the first extended mission. Several hundred scientific papers appeared describing SDO data. And we made it onto several "Best Of" lists and magazine covers in 2015! Many of these were for the excellent 5th Year movie showing how the Sun changed over the prime mission. SDO was built to show us how the Sun changes in time and having the movie be a "Best Of" image means we doing just that.

IFLScience Top 10 Space Images 2015

My favorite image of 2015 was the transit eclipse on Sept. 13, 2015. Here is an example of what that looked like in AIA 171. The sharp curve on the left is the Moon and the blurry curve at the top is the Earth moving out of the way. It was the first transit eclipse seen by SDO (probably a first for NASA) and the only lunar transit seen by SDO that was also seen as a solar eclipse on the Earth. Check out the movies of the transit eclipse at NASA.

I want to thank and congratulate the great team that works to keep SDO data and science flowing.

Even after almost 6 years in orbit SDO is GO!
