found the following FCC notice for more Spire satellite launches from Cygnus but I can't find any info on which launch this might be - any ideas?
SAT-LOA-20151123-00078 E S2946
Grant of Authority Effective Date: 04/07/2017
Launch and Operating Authority
Spire Global, Inc.
Nature of Service: Earth Exploration Satellite Service, Other
On April 7, 2017, the Satellite Division granted in part and deferred in part, with conditions, the application, as amended (File No. SAT-LOA-20151123-00078, as amended by SAT-AMD-20161114-00107), of Spire Global, Inc. Specifically, Spire was authorized to construct, deploy, and operate 4 satellites to be deployed from the Cygnus cargo vessel at orbital altitudes no greater than 500 km, as part of what Spire describes as Phase IB deployment. The satellites will be used to conduct maritime monitoring and meteorological monitoring operations. The satellites will operate using the 402-403 MHz (Earth-to-space) and (space-to-Earth) frequency band for telemetry, tracking and command and back-up data downlinking, and the 2020-2025 MHz (space-to-Earth) and 2200-2290 (space-to-Earth, for 1 MHz bandwidth operations with earth stations outside the United States) frequency bands. The satellites will also receive Automatic Identification System (AIS) and Application Specific Messages (ASM) signals in the 156.7625-156.7875 MHz, 156.8125-156.8375 MHz (space-to-Earth), and 161.9625-161.9875 MHz, 162.0125-162.0375 MHz, 161.9375-161.9625 MHz, and 161.9875-162.0125 MHz (Earth-to-space) frequency bands, and GPS signals centered at 1575.42 MHz and 1227.60 MHz (space-to-Earth) frequency bands. Action was deferred on the remainder of Spire's application, as amended.
(He forwarded info as he's away at the moment and can't easily access himself.)
