Alert Notice 365: Request to Monitor EF Eri for Hubble Space Telescope Observations

January 6, 2008: Dr. Paula Szkody (University of Washington) has requested our help in monitoring the magnetic cataclysmic variable EF Eri for upcoming Hubble Space Telescope observations. Confirming observations are requested to ensure that EF Eri is fainter than the safe observing threshold during the HST observing window on 2008 January 17 UT.

EF Eri is at RA = 03:14:13.20 , Dec = -22:35:43.0 (J2000).
