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).

April 23, 2008: Dr. Paula Szkody (University of Washington) and collaborators have requested our help in monitoring the cataclysmic variable SDSS151445 (SDSS J151413.72+454911.9) [PP Boo] for upcoming Hubble Space Telescope observations. Dr. Szkody requests nightly monitoring of this source beginning immediately, and continuing through 2008 May 10 UT at least. A follow-up AAVSO Special Notice will be issued when the HST observing window has been set.
SDSS J151413.72+454911.9 is located at RA 15:14:13.720,Dec +45:49:11.80 (J2000)
May 5, 2008: Dr. Paula Szkody (University of Washington) and collaborators have requested our help in monitoring the cataclysmic variable RE J1255+266 for upcoming Hubble Space Telescope observations. Dr. Szkody requests nightly monitoring of this source beginning immediately, and continuing through 2008 May 15 UT.
RE J1255+266 is located at RA 12:55:10.80, Dec +26:42:27.0 (J2000)
Edward Smith (STScI) has requested nightly photometric monitoring of the symbiotic star AG Draconis during the period 2009 August 2, and tentatively scheduled to continue through mid-September 2009.
Dr. Brian Espey (Trinity College, Dublin, Ireland) has requested photoelectric photometry and bright star CCD photometry of the semiregular variable V2105 Oph beginning immediately. These observations are in support of ultraviolet spectroscopy to be obtained with the Hubble Space Telescope on Wednesday, September 2, 2009. Observations are requested to continue through Sunday, September 6, 2009.
Dr. Brian Espey (Trinity College, Dublin, Ireland) has requested photoelectric photometry and bright star CCD photometry of the semiregular variable NSV 99 (= khi Peg) beginning immediately. These observations are in support of ultraviolet spectroscopy to be obtained with the Hubble Space Telescope in late October and late November 2009. Observations are requested to continue through the end of November 2009.
