subdaily

[Mark A. Mandel]

"These days, there are thousands of mailing lists -- mostly free, many
amateur, some exclusive, some not -- filling inboxes on a subdaily basis."
-- Wired Magazine, February 2002, page 95: "The In Crowd" by David
Streitfeld

Not in OED Online or Merriam-Webster Online. The evident meaning is 'more
frequent than daily', and Google has something like 280 hits which, at a
quick glance, are all technical from various scientific disciplines
(biology, astronomy...) and have this meaning.
