Note: As of June 2020, the REQUESTED OBSERVING CADENCE IS CHANGED. Please obtain at least one long light curve (time series) per month per observer while FO Aqr is in its high state. This cadence will help to enable keeping track of the rapidly changing spin period. The cadence should be higher if FO Aqr goes into its low state. - Elizabeth O. Waagen, 21 June 2020
October 10, 2017: Dr. Hauke Wörpel (Leibniz-Institut für Astrophysik Potsdam (AIP)) has requested AAVSO assistance in obtaining observations of the eclipsing intermediate polar (IP) candidate V902 Mon in support of an XMM-Newton observation scheduled for 2017 October 14, 14:42 UT (duration 43,000s).
September 6, 2017: Dr. Colin Littlefield (University of Notre Dame) and colleagues have requested AAVSO assistance in monitoring the intermediate polar cataclysmic variable FO Aqr beginning immediately. This campaign is similar to the one on FO Aqr requested by Dr. Littlefield and colleagues in July 2016 (AAVSO Alert Notice 545).
November 9, 2016: Further to AAVSO Alert Notice 545, time series observations of the intermediate polar cataclysmic variable FO Aqr are requested to provide simultaneous coverage of XMM-Newton observations scheduled for 2016 November 13 19:43 UTC to November 14 8:13 UTC.
July 13, 2016: Dr. Colin Littlefield (University of Notre Dame) and colleagues Drs. Peter Garnavich (Notre Dame), Erin Aadland (Minnesota State), and Mark Kennedy (University College Cork) have requested AAVSO assistance in monitoring the intermediate polar cataclysmic variable FO Aqr beginning immediately.
Dr. Littlefield, who with his colleagues recently published ATel #9216 and #9225, writes:
8 June 2012: Dr. Christopher Mauche, Lawrence Livermore National Laboratory, has informed us that the timetable of MAGIC telescope observations of the intermediate polar cataclysmic variable AE Aqr announced in AAVSO Alert Notice 458 has been revised. Here is the revised timetable for the dates in June:
REVISED TIMETABLE AS OF 8 JUNE 2012
2012 June
11, 1:43 - 2:26, UT
12, 1:39 - 2:22
13, 1:35 - 2:18
14, 1:31 - 2:34
