Bill,
I checked the occultation of HIP 83097 by 7 Iris on May the 22nd at 22h
1.4m UTC following the prediction by Ian Manek of IOTA es: with
surprise I found that Guide 8 (25 Feb version) places Iris 3.3 minutes
of arc off the target star. I downloaded the most recent version of
MPCORB from the Minor Planet Center web site. Same result.
Any idea?

Thanks,
Claudio Costa
