Successful prediction for the arrival time of the December 7, 2020 CME:

This CME is associated with a C7.4 flare from AR 2790 (S23W11) that peaked at 2020-12-07 16:32. The eruption signature of this event can be seen in SDO AIA 193/304 starting as early 2020-12-07 15:30.

Output from EAMv3 model:
Expected date and time for the arrival of the CME:
10/12/2020 - 00:23 UT.

The CME arrived on 10/12/2020 - 01:30UT just 1.10 hours later!

01 Dec 2020

Successful prediction for the arrival time of the November 29, 2020 CME:

This event is associated with a M4.4 solar flare beyond the south-east limb of solar disk, peacked at 29-11-2020, 13:11. This CME observed in the SE of STEREO-A COR2A (partial halo) and in the east of SOHO C2 starting around 2020-11-29 13:24 the CME front can later be seen in SOHO C3 at 2020-11-29 13:30.

For the first time, ASWFC utilized the new upgraded version of EAMv3.

Output from EAMv3 model:
Expected date and time for the arrival of the CME:
01/12/2020 - 21:13 UT.

The CME arrived on 01/12/2020 - 21:00UT just 0.22 hours earlier!

14 July 2020

Successful prediction for the arrival time of the July 9, 2020 CME:

This event is associated with a filament eruption visible between S30E05 and S30W25 in SDO AIA 193 imagery starting around 2020-07-08 20:32. The CME appears as a gradual brightening in the western streamer of STEREO A COR2 and later as a partial halo (southward) in SOHO LASCO C2/C3.

Output from EAMv2 model:
Expected date and time for the arrival of the CME:
13/07/2020 - 21:21 UT.

The CME arrived on 13/07/2020 - 20:35UT just 0.77 hours earlier!

12 March 2019

Successful prediction for the arrival time of the 8 March CME:

Active Region 2734 produced a C1.3 class solar flare on March 08 at ~03:20 and a CME noticed on LASCO C2 around an hour later. This CME seems to be geoeffective as it comes from the central meridian of visible solar disk.

Output from EAMv2 model:
Expected date and time for the arrival of the CME:
12/03/2019 - 03:52 UT.

The CME arrived on 12/03/2019 - 02:00UT just 1.87 hours earlier!

WELCOME TO ASWFC

From 2012 the Athens Cosmic Ray group developed a new facility in order to monitor the physical conditions of the near Earth space. This new facility named Athens Space Weather Forecasting Center - A.S.W.F.C. We provide in a daily basis a report of geomagnetic activity.
