# HALO CME ALERTS from the SIDC (RWC-Belgium), generated by CACTUS   #
#--------------------------------------------------------------------#
A halo coronal mass ejection (CME) was reported by the CACTUS automated
detection tool on Mar 16 03:14 UTC with a liftoff time Mar 15 06:36:07 UTC
directed towards the nord-east. This is an erroneous automated detection.
The CME that was observed in SOHO/LASCO-C2 Mar 15 around 05:00 UTC
originates from on the south-west limb and is not expected to impact the
Earth.#--------------------------------------------------------------------#
