Hi Anne,
Yes, apologies for the confusion. We had originally put the Doodle for 1400 UTC on Jan 30 but this conflicts with the SubPro IRT Meeting #26 which we assumed would present a conflict for many ASP Sub-Track participants, so we moved our ASP Sub-Track session to 1500 UTC. So, the calendar invitation you received for 1500 UTC is for the ASP Sub-track.
If that presents a conflict for you or others, please let us know. Thanks for your question and apologies for the schedule-switch!
Kind regards,
Kristy
