ACE Radiation Data

ACE Data Table.

ACE radiation data are plotted around periods when science runs were interrupted. Plots start exactly 2 days before the interruption started. The top panel shows differential fluxes of electrons 38-53 and 175-315 (particles/cm2-s-ster-MeV), the bottom panel shows differential fluxes of protons 47-65, 112-187, and 310-580 (particles/cm2-s-ster-MeV).

Two vertical red lines indicate the start and the end of the interruption. Purple hatched areas indicate that the satellite is in the radiation belt. The horizontal dashed line indicates P3 trigger level. If P3 level is higher than this level more than 2 hours, SCS 107 may be manually triggered.

Two vertical red lines indicate the start and the end of the interruption. Purple hatched areas indicate that the satellite is in the radiation belt. The red horizontal dashed line indicates SCS 107 limits. If the HRC shield rate/256 goes above 248, automatic SCS 107 is triggered.

ACIS Data

The following plots are copied from the ACIS Threshold Crossings Page. For more details, please refer to Using ACIS to detect and report high radiation conditions. All available plots for each day of the shutdown are listed. If a day is missing, then there is no plot available.


GOES-R Data

GOES Data Table.

GOES-R data are taken from NOAA site (https://services.swpc.noaa.gov/json/goes/primary/integral-protons-1-day.json).

P511.64 - 23.27 MeV protons (particles/cm2-sec-sr-MeV)
P625.90 - 38.10 MeV protons (particles/cm2-sec-sr-MeV)
P740.30 - 73.40 MeV protons (particles/cm2-sec-sr-MeV)

HRC Proxy is defined as:
HRC Proxy = 143 * P5 + 64738 * P6 + 162505 * P7 + 4127

Two vertical red lines indicate the start and the end of the interruption. Purple hatched areas indicate that the satellite is in the radiation belt. The red horizontal dashed lines indicate SCS 107 limits. If GOES P Channels or the HRC Proxy go above these levels, SCS 107 may be manually triggered.
