SUPERNOVAE (SN) AND ACTIVE GALACTIC NUCLEI (AGN) VARY ON TIMESCALES OF HOURS TO MONTHS AND ARE STILL SHROUDED IN MYSTERY. WE PROPOSE A LARGE K2 PROGRAM TO MONITOR ON THE ORDER OF 10 000 BRIGHT GALAXIES IN EACH OF CAMPAIGN C14 C15 AND C16 WHICH SHOULD YIELD IN TOTAL MORE THAN 15 GREAT LIGHT CURVES (LCS) OF SUPERNOVAE. IN KEPLER GO PROGRAMS WE HAVE IDENTIFIED TO DATE 3 SN IA (OLLING ET AL. 2015) 2 SN IIP (GARNAVICH ET AL. 2016; TUCKER ET AL. SUBMITTED) AND 1 SN IIN/IA-CSM (GARNAVICH ET AL. IN PREP.). WE ALSO FOUND THAT ~4% OF OUR GALAXIES DISPLAY AGN ACTIVITY WITH VARIABILITY AT>0.001% LEVEL (SHAYA ET AL 2015). IN K2 CAMPAIGN C3 C5 C6 C8 AND C10 WE IDENTIFIED MORE THAN 15 SNE THREE OF WHICH WE SPECTROSCOPICALLY CLASSIFIED. ANALYSIS OF THE K2 DATA IS ONGOING. WITH OUR PROGRAM WE PLAN TO A) DETERMINE THE TYPES OF COMPANIONS TO PROGENITORS OF SNE USING FEATURES IN THE EARLY BREAKOUT (T<4 DAYS) LCS; B) EXPLORE THE EXPLOSION PHYSICS OF SN ESPECIALLY SN IA USING SUBTLE FEATURES DURING THEIR RISE (T<20 DAYS); C) IMPROVE THE CALIBRATION OF SN IA AS STANDARD CANDLES FOR MEASURING DISTANCES HO AND DARK ENERGY USING K2 LCS OF UNPRECEDENTED DETAIL; AND D) ADD SIGNIFICANT KNOWLEDGE TO THE VIRTUALLY UNEXPLORED VERY LOW-EDDINGTON REGIME OF AGN. THERE IS AN ONGOING CONTROVERSY OVER THE BASIC PHYSICS OF ONE OF THE KEY TOOLS IN COSMOLOGY THE SN IA STANDARD CANDLE. DO SNE IA GRADUALLY REACH CRITICAL MASS VIA ACCRETION FROM A COMPANION STAR OR DOES IT MERGE WITH ANOTHER WD? IF A WHITE DWARF HAD BEEN ACCRETING MASS FROM A COMPANION STAR AS THE EJECTA REACHES THE COMPANION A SHOCK WOULD FORM WITH OBSERVABLE OPTICAL EMISSION (KASEN 2010). THE EMISSION WOULD BE SHORT AND STRONGEST FROM CERTAIN VIEWING ANGLES REQUIRING RAPID CADENCE FOR SEVERAL SNE BEFORE DEFINITIVE CONCLUSIONS CAN BE REACHED. FOR THE 3 SN IA DISCOVERED BY KEPLER MONITORING OF ~500 GALAXIES (OLLING ET AL. 2015) NO SIGNATURES OF A COMPANION WERE FOUND AND TIGHT CONSTRAINTS WERE PLACED. WITH A LARGER SAMPLE WE CAN DETERMINE THE STATISTICS FOR THE TWO POSSIBLE CHANNELS THAT TRIGGER SN IA. MEANWHILE FEATURES DUE TO THE DIFFERENT EXPLOSION PHYSICS (DETONATION DEFLAGRATION INWARDS-MOVING DIFFUSION WAVES ETC) OF IA AND CORE COLLAPSE SNE WILL ALSO BE REVEALED. K2 WILL ALLOW FOR THE FIRST TIME TO TEST MODELS MORE COMPLICATED THAN SIMPLE "EXPANDING FIREBALLS." WE WILL UNDERTAKE A MAJOR CONCURRENT GROUND-BASED EFFORT TO OBSERVE THE ENTIRE FIELD EVERY OTHER DAY USING SKYMAPPER ATLAS AND DECAM. WE WILL ALSO COORDINATE MULTI-COLOR PHOTOMETRY AND SPECTRA TO CLASSIFY DISCOVERED TRANSIENTS USING LICK GEMINI AND KECK. IN CAMPAIGN C5 AND C6 WE SUCCESSFULLY IDENTIFIED 4 SNE WITH DECAM OBSERVATIONS OF WHICH WE CLASSIFIED 2 WITH GEMINI SPECTRA AS SN IA. THESE DATA COUPLED WITH HIGH PRECISION 30 MINUTE K2 DATA WILL HAVE ENORMOUS LEGACY VALUE. METHODS: WE HAVE DEVELOPED AND PROVEN A HIGHLY SUCCESSFUL DETRENDING METHOD THAT SIMULTANEOUSLY SOLVES FOR THE SAWTOOTH PATTERN CAUSED BY POINTING MOTION AND FOR THE COEFFICIENTS OF VECTORS FROM PRINCIPAL COMPONENT ANALYSIS OF TARGETS ON THE SAME CHANNEL. THIS ITERATIVE TECHNIQUE PERMITS US TO DEFINE APERTURE SIZES BETTER SUITED TO THIS PROBLEM AND TO MAKE EXCELLENT CORRECTIONS FOR SENSITIVITY VARIATIONS ON ALL TIME SCALES. TO PROPERLY CORRECT SN LIGHT CURVES THE TECHNIQUE IS APPLIED TO THE QUIET TIME BEFORE THE EVENT AND THEN EXTRAPOLATED TO THE END OF THE CAMPAIGN.
