Significantly brighter than the other 13-14 mag comets on the same night. It looked similar to C/2003 WT42 in 2006, as it does on the CCD images.) 2007 9 23.17 S 12.8 HN 20.3T 133 1.0 4 GON Alto del Castro - Aralla, León (Comparison stars taken from Henden photometry near WW Cet.) 2007 9 20.16 S 13.0 HN 20.3T 133 0.8 5 GON Alto del Castro - Aralla, León (Comparison stars taken from Henden photometry near WW Cet.) 2007 9 15.16 S 13.0 HN 20.3T 133 0.8 5 GON Alto del Trichero - Soto y Amío, León (Comparison stars taken from Henden photometry near WW Cet.) 2007 9 13.967 S 12.6 TA 31.0J 109 0.9 2/ DIJ Sint Annen 2007 9 13.958 S 12.8 TA 31.0J 109 0.7 4 BOU Sint Annen 2007 9 10.02 S 13.2 HN 20.3T 133 0.8 5 GON Alto del Castro - Aralla, León (Comparison stars taken from Henden photometry near WW Cet.) 2007 9 8.10 S 13.2 HN 20.3T 133 0.8 5 GON Alto del Castro - Aralla, León (Comparison stars taken from Henden photometry near WW Cet.) 2007 8 16.16 S 13.5 HN 20.3T 133 0.7 5 GON Escuredo, León (Nearby field stars checked in DSS.
