Descripción
We conducted two multi-site campaigns for two previously poorly-studied rapidly oscillating Ap (roAp) stars, HD122970 and HD99563. In January-June 1998, we observed HD122970 with 7 telescopes at 6 observatories and obtained 119 hr of data. We decided to organise a larger campaign for the same star in the year 2001 (5 telescopes at 4 observatories, 203 hr of data in March and April), and included HD99563 as a target for the beginning of the nights. This star turned out to be quite interesting, wherefore we extended the observations until June 2001 and finally arrived at 125 hr of data, gathered with 7 telescopes at 4 observatories.
