2021 RG19
#11
Over the years, I've avoided magnitude estimates at Horizons. Horizons now appears to be getting better. In the new format, I would use T-mag for comets, APmag for asteroids. Those from the MPC seem to be more consistently correct vs true visual estimates. I've found the list at https://cometchasing.skyhound.com/ to be very helpful or to simply run an ephemeris in SkyTools. If I run the ephemeris using elements from the MPC for 2021 RG19, I get magnitudes brighter roughly a full magnitude - 14.9 vs 16.1.

The new format at Horizons has far more info than that from a week ago and the columns will not fit on my 27" 4k monitor. I've got to scroll to the bottom and then slide the columns and then scroll back up.
