See SDO 4k Movies and Projected over Dublin

Trinity College Dublin (Ireland) is running a campaign in Dublin called City of Physics, showing the city of Dublin the beauty of physics. For their opening nights at the end of October, they projected images from the SDO instrument onto a city centre building. A short video is available to show the reaction of people in the city is at Check out the undergraduate students busy talking to Dubliners about SDO.

When SDO was launched TVs were displaying 720p resolution. In the five years since we have seen TV screens at 1080p and now UltraHD (3840 pixels by 2160 pixels.) This means we can show half of the Sun in full SDO resolution on commercially available screens. As a result, NASA has released a new of 4k ultra-HD movies of SDO imagery. These are also on YouTube. But to get the full impact of the UltraHD resolution you need to download the movies from SVS website.

The SDO webpage also has a list of UltraHD movies. We are planning to start releasing daily UltraHD movies.

If only UltraHD allowed us to show the entire disk of the Sun at the native resolution of the SDO imagers! But that must await the next generation of screens.

Today is Calibration Maneuver Day!

SDO will perform two calibration maneuvers today. The EVE field of view maneuver will run from 1315-1557 UTC (9:15 am-1:57 pm ET) and HMI/AIA Flatfield will run from 1630-1907 UTC (2:30-5:07 pm ET). SDO science data will not be available from 1315-1910 UTC (9:15 am-5:10 pm ET), although the AIA near-realtime images on the SDO website will show the Sun running back and forth across the images.

Another Lunar Transit Today

SDO will see another lunar transit today from 1718 UTC (1:18 p.m. ET) until 1733 UTC (1:33 p.m. ET). Although this is a very short transit, the Moon will occult part of the fine guidance system in AIA so we will turn off the fine guidance during the transit. That means the AIA images will drift a little and the HMI Dopplergrams and magnetograms will not be created.

SDO Website is back up

The maintenance on the SDO web and data servers is complete the website is back up and running normally. Thank you.

SDO website is undergoing maintenance

The SDO web and data servers are undergoing maintenance and will be unavailable for a time. We apologize for any inconvenience. We will send out a message as soon as our servers are back up.

The First Maneuver of the First SDO Extended Mission

On October 1, 2015, SDO began the First SDO Extended Mission. The SDO Team submitted a proposal to NASA in March to continue observing the Sun for another two years. The proposal was approved and we began the extended mission on October 1.

With the extended mission comes calibration maneuvers. The first is an EVE cruciform today from 1800 UTC (2:00 p.m. ET) until 2230 UTC (6:30 p.m. ET). SDO science data will not available during the maneuver but the AIA images on the SDO website will look like the Sun is zooming around in space.

Congratulations to the SDO Team for the successful proposal and winning another two years of watching the Sun and solar activity!

Movies of the Alignment at NASA

NASA has posted a feature about the alignment yesterday morning. It looks great!
Check it Out!

I made a short video from the AIA jpeg2000 images. You can also make these movies at HelioViewer. The motion of the Sun is caused by the telescope heating up as the Sun rises. SDO cannot run its fine guidance system without seeing the entire Sun. During an eclipse the fine guidance system is turned off and a little while after the eclipse it is turned back on.
