Description

Comet Catalina displayed its dust tail as a broad fan 6 weeks ago. Now that Earth is close to the orbital plane of the comet we are seeing the thin dust fan edge on as a narrow spike.

The other effect of being close to the orbital plane is the very slow motion of the comet against the background stars as the comet is travelling almost directly away from Earth on this date.
