We present a sensitive search for WISE W3 (12um) and W4 (22um) excesses fromwarm optically thin dust around Hipparcos main sequence stars within 75pc fromthe Sun. We use contemporaneously measured photometry from WISE, remove sourcesof contamination, and derive and apply corrections to saturated fluxes toattain optimal sensitivity to >10um excesses. We use data from the WISE All-SkySurvey Catalog rather than the AllWISE release, because we find that itssaturated photometry is better behaved, allowing us to detect small excesseseven around saturated stars in WISE. Our new discoveries increase by 45% thenumber of stars with warm dusty excesses and expand the number of known debrisdisks (with excess at any wavelength) within 75pc by 29%. We identify 220Hipparcos debris disk-host stars, 108 of which are new detections at anywavelength. We present the first measurement of a 12um and/or 22um excess for10 stars with previously known cold (50-100 K) disks. We also find five newstars with small but significant W3 excesses, adding to the small population ofknown exozodi, and we detect evidence for a W2 excess around HIP96562 (F2V),indicative of tenuous hot (780 K) dust. As a result of our WISE study, thenumber of debris disks with known 10-30um excesses within 75pc (379) has nowsurpassed the number of disks with known >30um excesses (289, with 171 incommon), even if the latter have been found to have a higher occurrence rate inunbiased samples.
