as seen from Earth as in this 13 March
2013 California image from Kronk Cometography in which the Comet is a
faint dot far to the left of the Crescent Moon. However, an image from
a NASA STEREO
video during 9-12 March 2013
shows a Solar CME, Mercury, Comet PanSTARRS, and Earth to form an
interesting system. NASA says:
"... the tail looks quite complex and it will take computer models to
... understand ... what's happening ...".
Here are NASA STEREO images during 10-15 March 2013
as to which NASA says "... While it appears from STEREO's point of view
that the CME passes right by the comet, the two are not lying in the
same plane ... the comet's tail didn't move or change in response to
the CME's passage ...".
Here is a map from Astronomy Magazine showing the path of Comet
PanSTARRS during March, April, and May 2013:
