The newly expanded solar interferometer array at Owens Valley Radio Observatory (OVRO Solar Array) was in full operation with 5 antennas before and during the Max '91 Campaign that was associated with the HIREGS hard X-ray balloon experiment. For the two weeks prior to 1992 Jan 6, we obtained at least 21 flares within our UT time range of ~1600-2400 UT. During this pre-campaign period we were using an observing mode that measured 45 frequencies in both right- and left-hand circular polarization every 12 s. For the campaign period itself, from 1992 Jan 6-24, we obtained at least 10 large events along with many smaller ones. For the time that the HIREGS balloon was up, we were observing in a mode where we obtained only stokes I (total intensity), but at 20 frequencies with a 2 s cycle time to maximize our time resolution. In addition to the flare observations, OVRO is now capable of synthesis imaging of the active regions each day, which will be of interest for active region studies. We present early results from one or two of the best observed events by OVRO and other observatories participating in the campaign, including the event of 1941 UT on 1992 Jan 21. We emphasize multifrequency imaging of the flare as a function of time, a capability that is unique to the expanded OVRO Solar Array.
