One front side moving CME, appeared at 21:12 UT. It was very slow (202 Km/s; CDAW) and was moving toward south.
Unlikely to be related to 2013/01/18 disturbance
i) It was moving below the equatorial plane.
ii) initial speed is too low. Though true propagation speed could be greater than 202 km/s (CDAW), still it is very small.
