Comet C/2015 D1 (SOHO) and C/2015 C2 (SWAN) predicted paths as seen from Mayhill New Mexico. Click to embiggen.
Comet C/2015 D1 SOHO was a sungrazing comet that survived close passage to the Sun, only to disintegrate later.
People have been trying to follow the debris, evocatively called the "Ghost Comet" by Sky and Telescope, as it continues on the comets orbit.
As of March the 7th, the potential debris cloud will be higher enough for iTelescope instruments to catch it (northern scopes only) after astronomical twilight, and the Moon will be out of the sky.
The comet debris trail is only visible briefly at astronomical twilight and it will be quite dim (possibly magnitude 11-12). The MPC ephemeris is here:
CK15D010 2015 02 19.7471 0.028115 1.000000 234.7391 96.0501 70.2855 20141209 9.0 4.0 C/2015 D1 (SOHO)
Comet C/2015 C1 is the official name of the Comet ROB001 discovered in the SOHO SWAN images by Rob Matson and Michael Mattiazzo, and confirmed by Terry Lovejoy. It is too low for any of the iTelescopes, but will become visible from around March 27 on, probably around magnitude 12.

Comet 29P/Schwassmann-Wachmann has been reported to be in outburst, brightening to around magnitude 14.
Currently in Sagittarius, it is high enough for imaging from around midnight for the Southern iTelescopes and astronomical twilight from the northern iTelescopes. Please pass any observations on to comets-ml, comet-obs or the Comet Observation Database.
