CME: 2018-09-27T04:54:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: The source is a filament eruption seen in SDO AIA 304 around 09-27T04:00Z around S40E10. CME is very faint and difficult to measure. Start time may not be accurate. Some small disturbances were seen in the SW data, but nothing clear to determine the arrival of the CME.

CME: 2018-08-19T07:36:00-CME-001

Actual Shock Arrival Time: 2018-08-24T05:50Z

Observed Geomagnetic Storm Parameters:
----
CME Note: SIDC: In SoHO/LASCO C2 coronagraph images a very narrow (only around 10 degrees angular width) CME is visible from August 19 7:36UT onwards, directed towards the South-West. It is also visible from Stereo A COR2, also narrow and directed to the South-West from this viewpoint. The arrival time for this CME could have been confused with the arrival time of the 2018-08-20T21:24Z CME.

CME: 2018-07-05T04:39:00-CME-001

Actual Shock Arrival Time: 2018-07-10T11:25Z

Observed Geomagnetic Storm Parameters:
----
CME Note: This CME is visible in STEREO A COR2 on the W limb. It starts as a slowly brightening near the streamer before the CME is clearly visible. For this reason the start time can be anywhere between 02:39 (labelled by SIDC) and 13:09 (labelled by SWPC).

CME: 2018-03-06T23:54:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: Source is a filament lift off best seen in SDO AIA 304 from S10E25 at 2018-03-06T16:30Z. Start time is after the data gap from 2018-03-06T19:39Z to 2018-03-06T23:54Z in STA cor2 imagery. It is not visible in SOHO LASCO C2 or C3 imagery.

CME: 2018-03-05T23:39:00-CME-001

Actual Shock Arrival Time: 2018-03-09T23:30Z

Observed Geomagnetic Storm Parameters:
----
CME Note: First seen in STA Cor2 at 2018-03-05T23:39Z, but this is after a data gap from 19:30Z to 23:30Z so the true start time is uncertain. The source is likely the long-duration filling in of the dim CH region visible in the South of AIA 193, centered around longitude -10, beginning around 18:00 on 2018-03-05. The CME is also visible as a faint partial halo to the SW in C2/C3, but not visible in the difference imaging.
