FO Aqr monitoring requested now for HST observations
Abstract:
The campaign is critical for support of upcoming Hubble Space Telescope (HST) observations of FO Aqr. FO Aqr will be observed with the COS spectrograph, and there is concern that its detector could be damaged if FO Aqr is significantly brighter than normal (V~13.5 mag). The optical brightness of FO Aqr around the time of the UV spectra is important to help interpret the results.
Justification:
FO Aqr has gone through a series of low states starting in 2016, which prompted the new observations by HST. It is important to monitor the optical brightness to support the observations and avoid possible damage to the COS spectrograph. The nights of October 25/26 and October 27/28 are particularly important to get clearance for the HST observations.
