The HST ULLYSES program (see earlier threads for details) has added 2 more YSO targets for next week. These are in the Lupus clouds. It would be helpful to have BVRI photometry for them in order to help interpret the UV spectra. TESS will not be observing this region.
The targets are:
Sz 110
16 08 51.569 -39 03 17.71 V = 14.58 (Simbad) 14.67 - 15.33 V (VSX)
Start time: 23 May 2022 14:33:39 End time: 23 May 2022 18:31:44
Sz 114
16 09 01.849 -39 05 12.41 V: 14.12 (Simbad; not in VSX)
Start time: 26 May 2022 10:48:53 End time: 26 May 2022 19:33:09
Please add these targets to your observing lists, and observe at lest nightly through May 23 (Sz 110) or May 26 (Sz 114).
The HST observing times are not conducive to simultaneous observations from the western hemisphere; as usual the hope is to amass a sufficient number of points that we can identify any brightenings and fadings related to the accretion processes, to aid in the interpretation of the HST spectra.
Thank you for all the contributions you have made to this program to date.
Hi
Sz 114 appears to be V908 Sco which is in the VSX. Both SZ 110 and 114 have observations already in the AID from the earlier campaigns in April for other YSO's in the Lupus cloud.

You are correct…
Hi Andrew,
You are correct. Sz 114 is V908 Sco.

Hi Fred,
I have added observations of other fields for the targets of interest.
I also added two of the three new targets but will look in my observations if the thrid target is in the field.
Regards,
Josch
