Details/Specifics of Change:

A GOES-16/17 software patch (DO.08.01.00) is planned to go live on Thursday, September 19, 2019 between 1400-1600 UTC. No data outage will occur when the updates go live. These updates will result in changes to all Space Weather Level 1b (L1b) products as detailed below. GOES Rebroadcast (GRB) and GOES-R Product Definition and UsersM-bM-^@M-^Y Guide (PUG) impacts and updates are noted.

DO.08.01.00 Content

Algorithm | Title | Summary | GRB impact | PUG update
SUVI L1b | SUVI Image Serial Numbers | SUVI Image Serial numbers will be included in the L1b metadata. | no | yes
SUVI L1b | SUVI bad pixel table oriented incorrectly | Bad Pixel table will now be oriented correctly | no | no
SUVI L1b | SUVI Scale and Offset need to be dynamic | SUVI Scale and Offsets will now be dynamically calculated rather than statically configured | no | yes
EXIS, SEISS, MAG, SUVI | Revise algorithm_container attributes | Metadata updated to indicate this field is not in use. | no | yes
MAG L1b | MAG Arc Jet Correction | Applies a correction to compensate for arcjet firing effects. | no | yes
SUVI L1b | SUVI Remove automated contamination correction | SUVI automated correction was based on EXIS L1b daily averages. It is being removed. | no | yes
MAG L1b | Update Mag Shadow Flag Alg to Rev A | Implements an improved version of the algorithm reducing the false shadow indication window. | no | yes
SUVI L1b | SUVI yaw flip treated as 2-value instead of 3-value | Fix to the SUVI yaw flip flag to make it a 3 value flag instead of 2. | no | no
SUVI L1b | Update SUVI L1b to CDRL 80 Rev J | Contains 10 SUVI L1b algorithm updates. | no | yes
EXIS EUVS | EUVS Case Numbers Set Incorrectly | Fixes bugs that were preventing the EUVSCase Numbers to be set correctly. | no | no
EXIS EUVS | EUVS C Dark Mask Discrepancy | The EUVS-C variable called INTEGRATEDSIGNALSEUVSC_DARKMASK does not have the correct value. The discrepancy in this variable results in discrepancies in the other EUVS-C variables: lines, wings and Mg II index. | no | no
EXIS EUVS | EUVS negative currents | Remove the lines setting negative corrected currents to zero. | no | no
EXIS EUVS | EUVS time-dependent dark count correction | Adds a time dependent term to the dark counts equation. | no | no
SUVI L1b | SUVI Images Are Not Adequately Despiked | Exposure to energetic particles in orbit causes spurious bright pixels throughout the image. Analysis shows up to 2% of radiance in some images is the result of these spurious signals. This could significantly worsen in the case of a Solar Energetic Particle Event. A despiking algorithm is being deployed to deal with this contamination. | no | yes
EXIS XRS | XRS packet count | Update to the XRS packet count variable setting max range to 16383 and update to the long name. | no | yes
EXIS EUVS | EUVS Producing CaseNumber 0 With Bad Data | Changes the "missing data" error case number from 0 to 8. | no | no
EXIS EUVS | Update OMAS for EUVS 256 line | Updates the wavelength ranges for EUVS 256 nm line for both FM1 and FM2 | no | no
