It is crucial for our science goals that the first visit should occur as soon as schedulable in early January 2022 in order to provide an initial characterization of the coma of UN271 and to observe it at the maximum orbital plane angle when the Earth is ~3 degrees above the orbital plane of the comet.
Changes from submission 1:
Changed the aperture to UVIS2-2K2C-SUB. Changed the number of exposures per orbit from 5 to 6 orbits.
Changed the F438W filter observations to being F475X filter observations.
Changes from submission 2:
Fixed pos targs in the 12 exposures per two orbit visit to be properly dithered.
Changes from submission 3:
Changed aperture to UVIS2-C1K1C-SUB.
Added FLASH = 2 for the F606 exposures, results in no warnings in this ETC run:
https://etc.stsci.edu/etc/results/WFC3UVIS.im1666876/
Added FLASH = 7 for the F475X exposures, results in no warnings in this ETC run:
https://etc.stsci.edu/etc/results/WFC3UVIS.im1666875/
Added FLASH = 10 for the F814W exposures, results in no warnings in this ETC run:
https://etc.stsci.edu/etc/results/WFC3UVIS.im1666871/
Changes from submission 4:
Made minor edit changes to the proposal description.
Changes from submission 5:
Changed the timing requirement of the first visit to be between 2022 January 5 and 2022 January 12.
Changes from submission 6:
Ran Moving Object tool on 6 hour intervals between Jan 6 to Jan 11 in 6 hours intervals. Found possible star collisions within 6 hours of these times:
2022-Jan-07-00:00
2022-Jan-07-06:00
2022-Jan-08-12:00
2022-Jan-09-18:00
2022-Jan-10-00:00
2022-Jan-10-12:00
2022-Jan-10-18:00
All other times between Jan 6 to 11 look relatively free of bright background stars according to the DSS overlay in Aladin.
Also, I lowered the FLASH values for the F475X and F814W exposures as the coma will provide sufficient background in these filters to avoid CTE losses. I have kept the flash values in the F606W filter exposures the same.
Changes from submission 7:
Set timing requirements to 06-Jan-20221:18:00:00 to 09-Jan-2022:06:00:00
and
09-Jan-2022:20:00:00 to 12-Jan-2022:00:00:00.
This will avoid a bright star at RA, Dec = 02 11 40.69 -56 16 01.41 coming within 20 arcsec of the detector on Jan 9
and saturated stars from being on the same chip at RA, Dec - 02 11 43.19 -56 23 02.51 and 02 11 41.03 -56 22 22.97 on Jan 6.
Changes from submission 8:
Added timing exclusion band for Visit 1 of Jan 7 at 2 hr to Jan 7 at 15 hr.
Changes from submission 9:
Added exclusion bands for Visit 2 between 28-MAR-2022 to 03-APR-2022.
Changes from submission 10:
Added exclusion bands for Visit 3 between 8-JUL-2022 to 14-JUL-2022.
Changes from submission 11:
Added a third visit version of the science target and added exclusion bands for Visit 3 between 8-JUL-2022 to 14-JUL-2022.
Changes from Submission 13: added exclusion bands from 24-JUL-2022 to 09-AUG-2022.
Changes from Submission 14: added exclusion bands from 15-SEP-2022 to 22-SEP-2022.
Changes from Submission 15: added more exclusion bands until 09-OCT-2022.

The cause of its activity is unclear because this is beyond the heliocentric distance at which many common cometary activity-driving volatiles significantly begin to sublimate. We, therefore, propose to use six orbits of HST time over three visits to make high-resolution color maps of the coma of C/2014 UN271 determining its coma-centric color slope testing the presence of icy grains in its coma and to constrain the ejection velocity of the dust. Revealing the presence or lack of ice grains as the comet is inbound into the inner Solar System would provide direct observational constraints on whether its activity mechanism is driven by hypervolatiles. Determining the ejection velocity of the dust will provide independent constraints on the activity mechanism. In addition to determining the color map of C/2014 UN271, our observations will have legacy value for future interpretations of one of the few known large long-period comets, volatile content and evolution as it approaches the Solar System.We request a total of three visits, each consisting of two consecutive orbits to constrain the nucleus size and characterize the coma of C/2014 UN271 with WFC3/UVIS. We will acquire images in three wideband filters (F475X, F606W, and F814W) to image the distribution of dust and ice in the coma. The combination of these three filters allows us to use the dust color between 475 -- 814 nm to compare the gas and ice fraction, dust composition, and particle size in the ambient coma.
We will disable the gyro bias update for all orbits because we only require two consecutive orbits in each visit, and we do not require extreme pointing accuracy with the use of the full 40 arcsec field of view of UVIS2-C1K1C-SUB. This will result in an increase of 5-6 min of extra exposure time in each orbit.
The three visits will occur as follows:
1.) It is crucial for our science goals that the first visit should occur as soon as schedulable before the end of December 2021/early January 2022 in order to provide an initial characterization of the coma of UN271 and to observe it at the maximum orbital plane angle when the Earth is ~3 degrees above the orbital plane of the comet.
Observing the comet at this maximum orbital plane angle during the first visit will allow for a stereoscopic view of the comet crucial for our science goals when combined with observations taken at the minimum orbital plane angle in visit 3.
2.) The second visit of these observations should be carried out in late 2022 March/early 2022 April in order to observe UN271 as the Earth crosses its orbital plane with an angle of ~0 degrees.
3.) The third visit of these observations should be carried out in mid-2022 July in order to observe UN271 when the Earth is ~-3 degrees below the orbital plane of the comet.The team consists of members with extensive HST and comet observing, modeling, and data analysis. The entire team will be involved with the HST observations, reducing the data, interpreting the results, and rapid turnaround in the preparation of scientific publications. The PI Bryce Bolin (Caltech) has extensive experience in observing comets and reducing comet data contributing to a number of comet-related publications. Co-I Dr. James Bauer (UMD) is an expert at space-based observations of comets, nucleus extraction, and size estimation and on determining activity production rates including activity measurements from NEOWISE W2 band observations of 2I/Borisov. Co-PI Dr. Dennis Bodewits (AU) is an expert on comet activity and coma gas physics and brings extensive experience with space-based observing from missions, HST, Chandra, XMM-Newton, and the Neil Gehrels-Swift Observatory. Dr. Kevin Hardegree-Ullman (UA) is an expert on analyzing optical data from both ground and space-based observatories. Dr. Christine Chen (JHU) is an expert observer using space-based assets in multiple platforms and wavelength regimes that will assist in maximizing the effectiveness of the observations. Dr. Alessandro Morbidelli (OCA) is an expert on the dynamics and origins of small body populations and the interpretation of observational and cosmochemical data. Drs. Casey M. Lisse (APL) and Yan Fernandez (UCF) are expert comet observers with decades of experience observing comets from ground-based and space-based observatories such as Chandra, Spitzer, Hubble Space Telescope, and Deep Impact.Solar System Astronomy3falsefalsefalsefalsefalsetruefalseSUPPORTEDSOLAR SYSTEMYESCOMETC2014_UN271TYPE=COMET,Q=10.95346775840689,E=0.9995433744217906,I=95.56709024101407
