[Crater-team] Surprise SEP Event

[Harlan Spence]

Yes, thanks Kerry.  Both CMEs reported earlier seemed to be at or behind the limb.     Looks like we are now in our regular longer hiatus between real time passes.   Next one probably in five hours….we missed the onset with our R/T data but it will be interesting to see how it compares with our late October event when the next ground station comes into view.

My SRAG friends tell me it was a back-side event.  Imagery coming in now.   The CME coming off the west side there.

Do not open links or attachments unless you recognize the sender. If unsure, click the Report Phish button or forward the email to OPSEC.
I had an alert of multiple CMEs shortly ago – will try to hunt that down.

Hi Jody

Could you look at the solar wind data .. see if there is a shock or something.

There's no associated X-ray flare, and there was no CME passage in the forecast.  Is this a stealth CME, or an X-ray flare that's just on the far side of the Sun?

Also, looks like a sizeable SEP event is underway. No realtime CRaTER data available at this time but we should see elevated rates during the next pass - probably very soon!

CRaTER folks,



The CRaTER pipeline has finally processed DOYs 317 onwards.

Dozens of files spanning seven days had not been transmitted from Goddard, but we're caught up now.
