September 20, 2007: As announced in AAVSO Alert Notice 358, we are approaching the scheduled HST observing time for omi Cet (AAVSO 0214-03). Observations are currently planned for 2007 September 23, 19:00-23:30 UT. Dr. Margarita Karovska (CfA) and collaborators are using HST to observe Mira AB and study the behavior of the mass flow and mass transfer within this system. Optical observations -- visual and instrumental -- are requested for this campaign.
