Notes: First observations since November 13. The Met Office say November has been the dullest (i.e. cloudiest) since records began in 1929. Arp 118 appeared bright and was easily seen. Curious! It is an angular patch of light aligned roughly E-W. NGC 1143 is at the W end and 1144 marks the E end. The ends are brighter than the middle and the W end brighter than the E. The SE end (NGC 1144) seemed “squared off”. At the bottom of the drawing is a 6th magnitude star half the field diameter to the NW, so about 12 mins from the galaxies. |
