Gunslinger2-6 Posted July 23, 2021 Share Posted July 23, 2021 (edited) Data has been absent for more than 6 hours now. Scheduled maintenence or equipment failure? Edited July 24, 2021 by Gunslinger2-6 Link to comment Share on other sites More sharing options...
Christopher S. Posted July 23, 2021 Share Posted July 23, 2021 (edited) Could be that, could be diagnostics, but all of the ACE SWPC products have not updated for over 48 hours. It doesn't seem like data dropoff suddenly from the satellite, rather this seems intentional, so I doubt the satellite is compromised(for now). Give it a little while, we may get word from NOAA about it. If not, some of us can reach out and ask about it. Edited July 23, 2021 by Christopher S.

MinYoongi Posted July 23, 2021 Share Posted July 23, 2021 I think it might be scheduled maintenance. Maybe recalibration, maybe a bakeout or something else. Could be possible that ACE is sending Data but its not getting updated on our Info-sites rn, like Lasco sometimes on Holidays or Weekends. Link to comment Share on other sites More sharing options...
helios Posted July 23, 2021 Share Posted July 23, 2021 During scheduled maintenance, they usually report status 9: # Status(S): 0 = nominal, 4,6,7,8 = bad data, unable to process, 9 = no data However, EPAM is reporting Status 0 (nominal), but is transmitting invalid and missing data. But I've seen that happening before. So .. ¯\_(ツ)_/¯ Link to comment Share on other sites More sharing options...
HalfFeralHuman Posted July 23, 2021 Share Posted July 23, 2021 Looking at the WSA-ENLIL model, it looks like quite a complicated mash-up of plasma waves are overtaking each other in the satellite's approximate region. I wouldn't mind betting local magnetic reconfigurations are messing with the data, or that it went into a safe mode without being able to report a status change first.

Thanks for providing the rest of the information too. Everything seems to be up and running again! Edited July 24, 2021 by Newbie Link to comment Share on other sites More sharing options...
helios Posted July 24, 2021 Share Posted July 24, 2021 (edited) @Newbie Ah sorry I forgot to mention the source. The status is part of the data in text format: https://services.swpc.noaa.gov/text/ace-epam.txt Yes EPAM seems to be working again. But since this morning, the DSCOVR solar wind data (speed/density/temperature) is erroneous. Edited July 24, 2021 by helios Link to comment Share on other sites More sharing options...
