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
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:
