The target table below is being updated as each target is completed or rescheduled.  -  Elizabeth O. Waagen

Notes:  LL Lyr was not able to be observed due to issues with HST. It has been rescheduled for the 2023-2024 year of this campaign.   -  Elizabeth O. Waagen, October 24, 2023

Please observe LL Lyr nightly in anticipation of upcoming HST observations in September. An Alert Notice will be issued when it has been scheduled.  -  Elizabeth O. Waagen, September 5, 2023

Note:  RY Ser was scheduled for May and for June but was in outburst or too close to outburst to be a safe target. It may be rescheduled. GP Com observations did take place.  -  Elizabeth O. Waagen, July 5, 2022

GP Com observations will take place April 29-30, 2022; coverage is needed until May 20. See Alert Notice 775.  -  Elizabeth O. Waagen, April 27, 2022

The Alert Notice text below has been revised from the original version issued April 18, 2024.  - Elizabeth O. Waagen, April 19, 2024

Notes: HST will not be able to observe VY Scl at this time, so the observations have been canceled. However, the data being obtained by you continue to be extremely valuable to the astronomers, and continuing coverage is requested until after VY Scl has returned to its bright state. Thank you!  -  Elizabeth O. Waagen, January 31, 2024

Notes: Please continue observations at least through the 2024 observing season.  -  Elizabeth O. Waagen, July 2, 2024

HST observations were postponed. Please continue to monitor V452 Vul as instructed below until further notice.  -  Elizabeth O. Waagen, October 25, 2022

July 5, 2022

Note: Ongoing observations of T CrB are extremely important as the eruption predicted for 2024 draws closer. See HERE for more information.  -  Elizabeth O. Waagen, July 5, 2023, July 2, 2024

Please continue to monitor T CrB until further notice.  -  Elizabeth O Waagen, February 9, 2023

Notes: Post-outburst observations continue to be valuable and of interest. Please continue to observe RS Oph.  -  Elizabeth O. Waagen, July 2, 2024, September 30, 2024

Please continue to observe RS Oph, although the 2021 outburst is over. It returned to a fainter magnitude than before the outburst, so ongoing follow-up observations will be very valuable.  -  Elizabeth O. Waagen, April 4, 2022
