ALERT! Comet C/2015 D1 SOHO, ROB001 (SOHO SWAN) and Comet C/2013 C2 Tengagra, Observations Requested
Comet C/2015 D1 (SOHO) predicted path as seen from Mayhill New Mexico. The rectangle is the field of view of T14. Click to embiggen.
Comet C/2014 SOHO is a sungrazing comet that breifly reach magnitude 4 and survived close passage to the Sun, at least until it was out of the FOV of the SOHO C3 instrument.
Currently people are trying to recover it along its predicted path, however, because the orbital elements are from spacecraft observations, there may be a fair bit of error. Also the comet is very low to the horizon. To date, the comet has not been recovered and is likely to be dimmer than magnitude 9.
The comet is only accessible for northern hemisphere instruments, and will not be in view of the iTelescopes at astronomical twilight until around 4 March, when it will have dimmed a fair bit (possibly magnitude 11-12). The MPC ephemeris is here:

Comet ROB001 Comet ROB001 is a new comet discovered in the SOHO SWAN images by Rob Matson and Michael Mattiazzo, and confirmed by Terry Lovejoy. Sadly, while it is close to the star Beta Ceti, it is too low for any of the iTelescopes, and unlikely to become visible until after perihelion in April. You can generate your own elements here.
Comet C/2013 Tengara has been reported to be in outburst by the SLOOH robotic observatory, brightening from magnitude 19 to around magnitude 16. Currently in Corvus, it is high enough for imaging from around midnight. Please pass any observations on to comets-ml, comet-obs or the Comet Observation Database.
