Comet C2017/T2 (PANSTARRS)
This comet promises to be quite bright and circumpolar in the northern hemisphere. For this reason I have generated the following charts to help follow it.
- C/2017 T2 (PANSTARRS) 2019 Nov 1 - Nov 10 (in Auriga)
- C/2017 T2 (PANSTARRS) 2019 Nov 10 - Nov 20
- C/2017 T2 (PANSTARRS) 2019 Nov 20 - Nov 30
- C/2017 T2 (PANSTARRS) 2019 Nov 30 - Dec 8
- C/2017 T2 (PANSTARRS) 2019 Dec 8 - Dec 16 (entering Perseus)
- C/2017 T2 (PANSTARRS) 2019 Dec 16 - Dec 24
- C/2017 T2 (PANSTARRS) 2019 Dec 24 - 2020 Jan 1
- C/2017 T2 (PANSTARRS) 2020 Jan 1 - Jan 8
- C/2017 T2 (PANSTARRS) 2020 Jan 8 - Jan 16
- C/2017 T2 (PANSTARRS) 2020 Jan 16 - Jan 24
- C/2017 T2 (PANSTARRS) 2020 Jan 24 - Feb 1 (by the double cluster)
- C/2017 T2 (PANSTARRS) 2020 Feb 1 - Feb 9
Pointing to stars or date-labelled comet positions on each chart will show ephemeris data. The date-labelled positions are for 0h UT on those dates.
Sample star data
Star identifier, from Hipparchos/Tycho data
Visual magnitude, V
(variable stars are indicated)
Colour index, B - V
Sample comet data
Julian day, JD
Right Ascension
Declination
Distance from Sun, r
Distance from Earth, Δ
Angle from Sun, elong
Estimated magnitude, V
Stars shown in green squares have similar colour index to the Sun and so could be useful for magnitude comparisons.
NB: The magnitude could turn out to be very different from the estimate
