GOES-13 was taken out of storage on 19 June 2019 to begin a period of Image Navigation and Registration (INR) testing — the Satellite Data Services positioned a spare rooftop antenna to begin ingesting the GVAR data from the satellite (positioned over the Equator at 60.2º W longitude) . Visible images from 21 June are displayed above. According to NOAA: “With the established performance of NOAA’s new geostationary satellites, GOES-16 (as GOES-East) and GOES-17 (as GOES-West), and a healthy GOES-14 in reserve, NOAA can provide GOES-13 to the Air Force for their weather forecasting needs. After a check of the GOES-13 instruments, NOAA will operate the satellite on behalf of the Air Force during its remaining life span.”

A 5.5-hour animation of all five spectral bands of the GOES-13 Imager is shown below.

Water Vapor images from GOES-17 (GOES-West), GOES-15, GOES-16 (GOES-East) and GOES-13 (below) — all centered at Glasgow, Montana — showed the development of an anomalously-deep (for 21 June) mid-tropospheric cutoff low over eastern Montana. The images are displayed in the native projection of each satellite.

===== 25 June Update =====

A 23.5-hour animation of all five spectral bands of the GOES-13 Imager is shown above, centered over Wisconsin.

GOES-13 Visible images centered near Cape Verde in western Africa (above) showed that the INR quality of GOES-13 was still very good.

===== 26 June Update =====

A test of GOES-13 Rapid Scan Operations (RSO)was conducted on 26 June — a sequence of Infrared Window and Visible images (above) revealed the presence of a Mesoscale Convective Vortex (MCV) off the US East Coast, following the dissipation of its parent nocturnal thunderstorm.
