| 184P/Lovas (passing through Aquarius) Sun Distance 1.70 AU Earth Distance 1.06 AU (159.0 million km) Atttempted observation of comet 184P/Lovas but after checking the image against a DSS2 reference image using Aladdin, it was determined that no indication of the comet was visible at the expected location (circled) and expected magntiude (+15.9) |
Image Detail Comet's expected position indicated by white circle in image below. Whilst attempting to identify the comet and rule out candidate objects in the vicinity it was noticed that one star was at a slightly different position compared to its position in the DSS2 reference image. The star was determined to be LP 739-36, a high proper motion star |
