SN 2008ft is located at R.A. = 3h50m18s.54, Decl. = +70o05'46".4 (equinox 2000.0), which is 18" east and 6" north of the center of the galaxy UGC 2866. Nothing is visible at this position on a Palomar Sky Survey F plate (limiting red mag 20.8). There is a bright area at the position of 2008ft on a Palomar Sky Survey N (near-infrared) plate, but when they compare images of 2008ft to the discoverers' own reference images from Aug. 29/30, they note a very clear brightening at this position. Editor's note: Due to a glitch in the archiving algorithm for newly designated supernovae (which should now be corrected), SN 2008ff (cf. CBETs 1488, 1508) was not properly inserted into the Central Bureau's lists of supernovae (either internally or that posted at the website URL http://www.cfa.harvard.edu/iau/lists/RecentSupernovae.html); thus, it was missed during the running of normal searches for known objects when the report (cf. CBET 1514) of a new supernova in ESO 284-G32 was received from M. Hamuy (despite the findings of the subsequent search for prior- received e-mails for objects at that same position, which produced the report by Tan). As the object announced as 2008ft on CBET 1514 is clearly identical with the type-Ia supernova 2008ff, the designation 2008ft is being now re-used for the new supernova announced above.
