Summary0001703: Comets do not always appear on sky charts
DescriptionSometimes comets are not shown on the sky charts. I have the box "Show comets on the chart" checked and I switched from "Proportional to the tail length" to "Display as a symbol" and noticed that, for example C/2017 E4 (Lovejoy) did not appear on the sky charts, even if I changed to "Show comets 14 magnitudes fainter than the stars." box.

I cannot reproduce the problem.

Maybe something get wrong with your comet database.

Can you try the following:
- open Setup / Solar system / Comet / Data maintenance
- on the line "Quickly delete all data related to comet" click the Delete button.
- go to tab "Load MPC file"
- click the Download button.

Do this solve the problem?

I still use the COMET-2017-03-31.DAT that came with the latest beta. I can not provide the steps to reproduce it, as the problem happens sometimes and not always. I will update the MPC file and report back if it happens again.

I just noticed another issue related to comets. Some labels of comets disappear when rotating the sky charts. For example C/2017 E4 (Lovejoy), C/2015 ER61 (PANSTARRS), 81P/Wild etc. See images.
