Hi Mati and All, Regarding Paul Camilleri's discoveries, I have a hand written letter by Paul dated 1991 Sept 21 in which he lists his discoveries to that time, including HDE331015 in Ara as PC5. This star was constant near magnitude 10 on 9 photos between 1990 May 18 and 1991 March 13. Two photos, however, showed it fainter than 12. In a later letter of 1992 Sept 15, HDE 331015 was omitted from his updated list as he felt he had made an error with this star and it was replaced by NSV4721 as PC5. HDE331015 was therefore omitted from IBVS 3923. Visual observations by several Australian observers have show HDE331015 to be an Algol type variable ranging between approximate magnitudes 11.0 and 13.4 with a period near 9.4169 days. Epoch for minimum light was determined as GJD 2450311.9775 + 9.4169 days. This was summarised in vsnet 1691 of 1998 Oct 18. Based on this HDE331015 is now V871 Ara in the 75th Name List and should therefore be included in any listing of discoveries by Paul Camilleri. CCD photometry of V871 Ara by Colin Bembrick and Tony Ainsworth appeared in Southern Stars 40, 4, 2001 December, giving a new period and epoch for primary minimum of HJD 2451733.8759 + 9.4165 days. Incidently, NSV4721 Vel (the current PC5) is discussed in vsnet-chat 3841 of 03 Dec 2000.
