Following the detection of GRB 141026A by Swift (Hagen et al. GCNC
16950), observations with the IRAM 30m antenna (+GISMO) at Pico Veleta
(Spain) were triggered on 26-27 Oct. At the position of the optical
afterglow (Littlejohns et al. GCNC 16952, Varela et al. GCNC 16953,
Gorosabel et al. GCNC 16954), we detect no mm afterglow (at 2 mm) down to
a preliminary flux density of 1.2 mJy (3 sigma) on Oct 26, 14:30 UT (mid
time). We acknowledge excellent assistance from the IRAM observers.
