Latest images from the Solar Terrestrial Relations Observatory (STEREO - EUVI/COR1/COR2/HI1/HI2)
Downlink from STEREO Behind has been detected during the recovery track on August 21st 2016. More info | All news.
Solar TErrestrial RElations Observatory (or STEREO) employs two nearly identical space-based observatories. One ahead of Earth in its orbit (STEREO A), the other trailing behind (STEREO B) to provide stereoscopic measurements to study the Sun and the nature of its CMEs. Check the current STEREO positions and ground station coverage.
Beacon images
These are the latest received images from both spacecraft. They are generally of lower quality and resolution. Some factors such as Deep Space Network schedule conflicts may result in delaying the beacon images. Check below for the latest high-resolution images (these are normally delayed by up to 72 hours).
Note: Both HI1 and HI2 images are processed using two different methods. You can swap the different versions by clicking on the full-size image in the popup window.

note: The "rdiff" COR and HI images use different type of postprocessing called "running difference". It detects the difference between the current and the previous available frame, thus providing a highlight on the subtle details in the images.

STEREO Weekly Meeting Minutes for 2019-01-15 (Week 3) ANNOUNCEMENTS ------------- * None. INSTRUMENT and SPACECRAFT STATUS -------------------------------- * Ahead is operating nominally. * Four years after the initial loss of communications anomaly with the Behind observatory, NASA has directed to cease periodic recovery operations with the last support on October 17, 2018. DISCUSSION AND OPERATIONS CONSTRAINTS ------------------------------------- Week 2 (Jan 7-13) * On day 009 (Jan 9), the fifth acceptance test of the CCSDS SLE bluebook version 4 software update between the Ahead MOC with the DSN was conducted. While SLE telemetry and command binds were successful, multiple commands could not be sent due to an issue with the candidate ground software release which was resolved the next day. One additional test with the DSN will be requested for ground software validation. * On day 013 (Jan 13), during the DSS-35 support for Ahead, the transmitter tripped off-line at 0321z. The transmitter was recalibrated and the uplink was re-established at 0335z. This anomaly resulted in the loss of 14 minutes of commanding and two-way tracking data and 13,971 frames of real-time telemetry and SSR data. See DR# C113911 for more information. * The average daily science data return for Ahead was 5.8 Gbits during this week. * There was some additional discussion about continued support from the various teams during the government shutdown. IMPACT, who was not at last week's meeting, continues to work normally. JPL reports that they're funded at least through the end of January, but are uncertain about February. The FDF reports that they're able to operate through the end of February. The schedulers are considered essential NASA personnel, and will continue to function, as will the SSC. Week 3 (Jan 14-20) * The 5th SLE version 4 test with ESA was carried out successfully. * Ahead has twelve passes during the week, and overall coverage is nominal. There are nine passes at 720 kbps, two at 360 kbps, and one at 240 kbps. Week 4 (Jan 21-27) * The Martin Luther King federal holiday occurs on Monday, Jan 21. This is not a holiday at APL. * Ahead has 11 passes during the week, and overall coverage is nominal. There are eight passes at 720 kbps, one at 360 kbps, and two at 240 kbps. Week 5 (Jan 28-Feb 3) * The 116th momentum dump on Ahead is scheduled for Wednesday, Jan 30, with ignition at 21:00 UT. This is the 35th dump without using the gyros. * Ahead has 9 passes during the week, and overall coverage is nominal. There are six passes at 720 kbps, two at 360 kbps, and one at 240 kbps. Week 6 (Feb 4-10) * Ahead has twelve passes during the week, and overall coverage is nominal. There are eight passes at 720 kbps, two at 360 kbps, one at 240 kbps, and one at 160 kbps. Week 7 (Feb 11-17) * The 46th SECCHI stepped calibration roll is scheduled for Monday, Feb 11, with ignition at 10:15 UT. This is the midpoint roll. System momentum is expected to be 7 N-m-s. * Ahead has nine passes during the week, all at 720 kbps, and overall coverage is nominal. Week 8 (Feb 18-24) * Ahead has ten passes during the week, and overall coverage is nominal. There are seven passes at 720 kbps, and three at 360 kbps.
