184P/Lovas - Attempted Sighting, Oct 2020

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
