C/2011 L4 (PanSTARRS)

[Mariusz Kuźmiński]

I'll be very grateful if somebody share correct orbital data with me! At the moment I'm using following lines:

EllipticalOrbit
{
Epoch 2456306.5
Period 3.168808464522018E+92
PericenterDistance 3.015492435598970E-01
Eccentricity 0.999964555305765E+00
Inclination 8.420747171680337E+01
AscendingNode 6.566595610452181E+01
ArgOfPericenter 3.336507595024000E+02
MeanAnomaly -6.929257029603301E-05
}

but it works wrong. The comet is above 1.5 AU from Earth and isn't visible from Poland in the evening It's still visible only from southern hemisphere

Try this

EllipticalOrbit
{
Epoch 2456361.6696
Period 914738.059217441
PericenterDistance 0.301542
Eccentricity 1.000032
Inclination 84.2072
AscendingNode 65.6658
ArgOfPericenter 333.6518
}


It is made from today's data at Minor Planet center
