Smalley of the Minor Planet Center, a very close approach to the Earth in 2029 now seems likely but any impact is precluded. Currently the PHA Close Approaches to the Earth webpage at the Minor Planet Center gives the close approach on 2029 Apr. 13.91 and distance 0.0002262AU from the centre of the Earth, which is just below geosynchronous orbit. During its close approach, it is likely that tidal torques will significantly alter the object's spin state. SUPERNOVA 2005V IN NGC 2146 Discovery by Nuclear Supernova Search campaign with the William Herschel Telescope of a possible supernova (IAUC 8474): SN 2005 UT R.A. (2000.0) Decl. Mag. Offset 2005V Jan. 30.16 06 18 38.28 +78 21 28.8 13.8K 1.8"E, 3.4"N Tom Boles, Coddenham, England reports that his image, taken at the request of the Central Bureau, and reaching magnitude 20.5, did not allow this object to be definitely separated from the bright core of the host galaxy. SUPERNOVA 2005W IN NGC 691 Discovery by Yoji Hirose, Japan, of a possible supernova (IAUC 8475): SN 2005 UT R.A. (2000.0) Decl. Mag. Offset 2005W Feb. 1.44 01 50 45.75 +21 45 35.6 15.2 56"E, 1"S There is also a foreground star of mag 17.6 at position end figures 45.46a, 38.6". SATURN XXXII Further to the note on E-Circular 2087 regarding the satellites of Saturn, Mark Bailey has drawn our attention to the naming of Saturn XXXII. It appears a correction to IAUC 8471 was issued by the Central Bureau and that the correct name is: Methone (= S/2004 S 1) SUPERNOVA 2005X IN ANONYMOUS GALAXY Discovery by LOSS/KAIT of a possible supernova (IAUC 8476): SN 2005 UT R.A.
