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

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.
