114P/Wiseman-Skiff  - Comet

114P/Wiseman-Skiff - 2020-03-03
(passing through Orion)
Sun Distance 1.66 AU
Earth Distance 1.29 AU (193.4 million km)
No sign of comet at expected position. 
Comet is receeding and has most likely become too faint ?
   114P/Wiseman-Skiff - 2020-03-03, Detail
Autoguided on offset star using PHD2 with Lock Shift
set at the comet's expected rate of motion
(Ra 90.89  arcsec/hr, Dec -14.22 arcsec/hr)
No definite sign of comet at expected position
- a very faint light signature may or may not be the comet.
