With the coming of spring and summer with the nights shortening I would like to ask about the value of uploading partial eclipses.
I did notice some in the Exo Watch database. How valuable are they and any rules or advice about them?
Thanks Andrew
I asked my Mentor…
Hi Andrew
I asked my Mentor that very question. His response was that there certainly is value in partial observations. I’ll have to search out his response and see what, if any specifics, he added to that generality.
In general, I’d suspect it would be useful to capture both ingress and egress points as well as as much baseline as possible on one side or the other of the ‘dip’. I might run later, or start earlier to make up for lost baseline on the other side. I’d try to avoid further compromises by not having a meridian flip within the observation. I’ll let you know if I find anything else in his email….assuming I can find it.
cheers

ps: someone smarter than I will chime in I hope.
Yes, partial eclipses are useful, especially if:
1. They cover a good amount of pre-ingress or post-egress baseline
AND
2. They cover some amount of the transit past the predicted midpoint.

Thanks all for the information. Regards Andrew
