The 24 μm cutout images for the MIPS‐1, MIPS‐2, and MIPS‐3 observations. The images, oriented in equatorial coordinates with north up and east to the left, span ﹩210^{\prime \prime }\times 110^{\prime \prime }﹩ with a pixel scale of 2﹩\farcs﹩45 pixel−1. The arrow highlights the position of Var Her 04, emphasizing the appearance of the cataclysmic variable in MIPS‐2 and its absence in MIPS‐1 and MIPS‐3. MIPS‐4 (not shown) appears identical to MIPS‐3. The circled stars are the four stars used for comparison in the ensemble differential photometry.
