GOES-12 X-ray Position Electronics (ERPE) Anomaly
This anomaly makes it impossible to track the Sun in the north-south direction and has impacted the mission of the XRS and SXI instruments. View the for a graphic account of this anomaly's effect on SXI.

GOES-12 SXI Operations Resume in TEST MODE ONLY
Images collected during this test phase have no scientific value.
February 7, 2007 20:48 UT
GOES-12 SXI Placed in Safe Mode
Due to some uncertainty about the state of the SXI instrument, it was decided to command the GOES-12 SXI to safe mode. An engineering review will determine the next course of action.

GOES-12 Commanded to Safe Mode
Due to yesterday's light leak anomaly, GOES-12 has been placed into safe mode as a precaution.
September 18, 2006 19:35:43UT
GOES-12 light leak anomaly
A major new off-band light leak appeared in the GOES-12 SXI images starting at 2006-09-18 19:35UT. The image taken with the PTHNB analysis filter at 19:34:02UT seems fine. The image taken at 19:35:43UT shows a major new off band light leak that has persisted since its first occurrence. An image taken between these two images, at 19:35:02UT, shows a severely attenuated X-ray image of the Sun. ) The failure was probably taking place during this exposure. The most likely failure mode would be one or more segments of the entrance filters failing. Perhaps at 19:35:02UT a filter was curling over on itself cutting down the X-rays.

The GOES-12 SXI data flow resumes.
February 12, 2006
The GOES-12 SXI experienced a high voltage system anomaly on
Sunday February 12, 2006 at approximately 1104 UT and automatically
went into safe mode. At first glance the anomaly appears to
be in the same class as the previous sets of HV problems.
SXI will remain in safe mode while SWPC and SOCC staff analyze
the telemetry available and plan our response.

Martin Luther King-storm movies added to Greatest Hits page.
GOES-12 SXI recorded a series of X-class flares from January 15
- 20. Two special movies were generated that illustrates this
interval of high activity. SXI performs double duty by recording
solar images and energetic ions!

New GOES-12 SXI Coronal Hole Product
Beginning on Dec 15, 2004, NOAA/Space Weather Prediction Center started
routine production of a coronal hole image product. This product
is created 4 times per day (01:00, 07:00, 13:00, and 19:00
UT), for the purpose of identifying coronal holes, and they
become available at approximately 08:00, 14:00, 20:00, and
02:00 UT. Each coronal hole image is created from a sum of
12 hours of images (corrected for solar rotation), spanning
the period 6 hours prior to the nominal coronal hole image
time to 6 hours after . The coronal hole image is composited
from 3-second integration, Level-1 (calibrated) images taken
through the Thin Polyimide (PTHN) filter.
The need to create this new product was driven
by the loss of the ability to use the SXI Open Filter position
and by anomalous high voltage power supply (HVPS) behavior.
The inability to use the Open Filter was caused by the failure
of at least 1 of the 6 entrance filters that normally shield
the SXI optics from visible and ultraviolet light. The HVPS
behavior has forced imaging to be conducted at a lower than
desired gain.
The SXI Coronal Hole product is now available
online. View these data in the Browse and Movie sections.
