Added a pointing offset of POSTARGX=-20”, POSTARGY=-10”, such that 29P is away from the chip gap into UVIS1 by ~20”, and towards the west side of the chip by 20”. 2. Added a relative pointing offset between the two visits in each consecutive pair with delta_POSTARTY=1.5”. 3. Added an offset between the two F487N exposures by delta_POSTARTX=-0.1 and delta_POSTARGY=2” to dither off the chip gap and bad pixels 4. Decreased the exposure time of F487N by 25 s to accommodate the pointing maneuver. --------------- Update 10/3 16:10 Correct the sign of POSTARG parameters for the correct pointing. --------------- Update 10/22 11:20 Update the sequence to better serve our science goals.

Receipt: # 15965-10 Visits 37 and 38 have been scheduled and cannot be changed. Visits 47 and 48 are added to replace 37 and 38. Visit Planner returns error probably due to the fact that the time linked visits 37 and 38 are already scheduled. Comet outburst target of opportunity We request 6 orbits of observing time to investigate the aftermath of a >1 mag cometary outburst using WFC3/UVIS. The goal of this project is to connect larger cometary outbursts detectable from Earth (>10^6 kg) with smaller outbursts seen by Rosetta and Deep Impact (<10^6 kg) to determine what processes drive them and to evaluate their effect on comet evolution. We will characterize the morphology and amount of the ejected material, use its color to evaluate its ice content, and search for fragments. This is a ToO observation with the target to be identified based on the triggering criteria: A comet that has just undergone an outburst of >1 mag in total brightness. The observing plan described here is therefore a skeleton sequence and is subject to adjustment based on the particular target identified. The items to be adjusted could include: 1. Name and orbital elements of target. 2. Exposure time. 3. Optional exposure settings such as FLASH. 4. Probaly apertures. We will observe the target in three epochs, separated by about a week, with two consecutive orbits in each epoch. All six orbits will contain similar sequence, nominally with one exposure from each of the two medium-band filters, F689M and F845M, and two long-exposure from the narrow-band F487N with 2x2 binning in between. If more time available in each orbit, depending on the brightness of the comet and the likelihood of producing fragments from the outburst, we will either add more medium band exposures to boost the signal-to-noise ratio of the color ratio map, or add a long exposure with F350LP for a deep search of fragments. The exposure time for medium-band filter is tentatively set to be 250 s, and for narrow-band filter F487N 500 s. Based on our previous observations of 46P/Wirtanen (HST-GO15372), this exposure time will result in appropriate exposure level (1/3 saturation level) at the center region for a comet of 2 mag fainter. We will adjust the exposure time based on the brightness of the comet we pick, and the previous observations of 46P and other comets through the same filters. In order to avoid bad pixels/columns, we will offset the pointing in the second orbit in each epoch by (1", 1") using the POSTARG parameter. --------- Update 10/01/2019 (JYL): Remove 2x2 binning, and adjust the order of exposures for Bright Comet case (11, 12, 21, 22, 31, 32). Adjust exposure times to fill up the visibility for all visits. New exposure time: F487N 470 s in visit 11, 21, 31; F689M and F845M 400 s in visits 33 - 38; F470N 650 s in visits 33-38. Add or adjust FLASH as needed. The team has extensive experience with HST and consists of expert observers, modelers, and data analysts, who have developed sophisticated techniques for measuring and interpreting comet activity and composition. All team members will aid in integrating the results from the different instruments and will be involved in the preparation of scientific publications. The PI and team leader Dennis Bodewits (Auburn U.) is an expert on comet activity and coma gas physics and brings experience with the Rosetta and EPOXI comet missions. He has led several comet observing campaigns for several orbiting telescopes, including comet observations with HST, Chandra, XMM-Newton, and the Neil Gehrels-Swift Observatory. Jian-Yang Li (PSI) is an expert comet observer who has successfully led and/or participated in over 20 HST programs. Drs Michael S.P. Kelley (U. Maryland) and Quan-Zhi Ye (CalTech/IPAC) are expert dust modelers and lead the outburst detection and follow-up programs on the ZTF and the facilities provided by the GROWTH network. Dr. Silvia Protopapa (SWRI) is a solar system ice expert who will be in charge of the interpretation of the color imaging. Dr. Emmanuel Jehin (U. Liege) leads the comet monitoring program at the TRAPPIST facility that will provide baseline gas and dust production rates and rapid follow up using comet-specific filters.
