VERITAS observed the bright blazar 1ES 2344+514 during two flaring periods, one from Dec.
17 to Dec. 18, 2015 (MJD 57373-57374) with a peak flux of ∼60% of the Crab and another from
Nov. 28 to Dec. 3, 2021 (MJD 59546-59551) with a peak flux of ∼20% of the Crab. This blazar,
located at a redshift of 𝑧 = 0.044, is classified as an extreme high-frequency-peaked BL Lacertae
object (HBL). It is known to be variable, including several previous day-scale flares: Whipple
on Dec. 20, 1995, VERITAS on Dec. 7, 2007, and MAGIC on Aug. 11, 2016. The VERITAS
near-nightly monitoring of 1ES 2344+514 during the 2015-2016 and 2021-2022 seasons provides
good coverage of the pre- and post-flare flux as well as the rise/fall time of the flares. We present
the multiwavelength light curves of each flare as well as the very high-energy spectra in the two
flare states and the two pre-flare states.
