Richard Nowell, Glenn Lindsey report/s the discovery of a new astronomical transient.

IAU Designation: AT 2014fu
Coordinates (J2000): RA = 02:44:04.848 (41.0202) DEC = +00:46:28.92 (0.7747)
Discovery date: 2014-09-30 06:56:13 (JD=2456930.7890394)

Potential host galaxy: SDSS J024403.83+004629.6
Host redshift: 0.045

Remarks: This transient was first noticed in a discussion on the Galaxy Zoo website at this address: https://www.zooniverse.org/projects/zookeeper/galaxy-zoo/talk/subjects/21665590. The discussion was started by Glenn Lindsey (participant snugthejoiner), Rick Nowell made the initial discovery that was confirmed by participant CeciliaB. DECaLS address is: http://www.legacysurvey.org/viewer?ra=41.0202&dec=0.7747&zoom=16&layer=decals-dr5

Photometry

Discovery (first detection):
Discovery date: 2014-09-30 06:56:13
Flux: 22.19 ABMag
Filter: R-Cousins
Instrument: DECAM
Telescope: CTIO - 4-m Victor M. Blanco Telescope

Remarks: The apparent magnitude was calculated using APT and the guide object SDSS J024400.64+004723.0 http://skyserver.sdss.org/dr14/en/tools/explore/Summary.aspx?id=1237678617435766979. The DECaLS r-band magnitude of 19.05 was used as a reference. As the apparent magnitude was quite dim, probably because the transient had not yet reached its full luminosity, the absolute magnitude was also calculated as -14.2583 (no k-correction).
