The new version of LOIS will have single-amp mode and allow the aborting of scripts. Over the next month we also will be implementing an "occultation mode" that will fix the timing error and enable the high-speed readout of a subframe. We would like to use this mode for MagIC to observe a stellar occultation by Charon in July. This occultation work is in collaboration with Dave Osip, who has duPont time. Assuming that our upgrades and testing at MIT continues according to plan, we are looking at shipping the computer to LCO at the next available opportunity. Julie Kane and I would stay a few days after our June run on the Clay (June 6-9) to switch MagIC over to the new computer. This work could be done with no impact on the scheduled observer(?), since we would be working in the room that houses the MagIC Sun and not require any time on the sky. If all the modes appear to work, we would hope to take some dome flats during the day, if that would be possible. If the modes do not work, we would attempt to ascertain the reason. One extreme possibility for things not working with the new software would be a wiring error in the dewar. At that point we would have to have someone come to Chile to fix the wiring error (or ship the dewar back to MIT for inspection and repair). Following this engineering work, the next step would be to get some time on the sky during the next engineering run on the Clay (the three nights of June 21-23). 1) What are your thoughts on this general plan? 2) Where should we ship the new MagIC computer to go with your next general shipment to Chile?

SHIPPING THE COMPUTER The easiest way to ship the computer is to send it to Pasadena where it can be loaded into our May air shipment. It should arrive in Pasadena by May 9, 2005 and we would bill you for the shipping cost when we receive the invoice. You should send a description of the equipment and its dollar value to Earl Harris, along with your contact information and an address for billing (important). Ship the computer to: David Osip c/o Alan Uomoto (important, or Dave might be billed for shipping) 813 Santa Barbara Street Pasadena, CA 91101 626-577-1122 Earl will mark it for David Osip/MagIC and put it in the air shipment. DAYTIME ENGINEERING AT LCO The post-June 9 computer installation part of your engineering plan looks OK to me, although Frank should check to make sure it makes sense with his crew schedule. I think it's important that Dave Osip be on-site as a science collaborator while this work is done. I think it's risky to plan on shipping the dewar back to MIT for repair if you have an occultation date in July so you should be prepared to have someone come to LCO for the modifications. You will probably also want to make sure that the possibility of MagIC not being available for the end-of-June MIT run is acceptable. NIGHTTIME ENGINEERING AT LCO I have been thinking about June engineering on Clay and the preliminary plan suggests a fair amount of high priority work on LDSS and lower priority work on the guider at the MIKE port. If all you need is a night to check out of your finished work, I don't think it'll be a problem. If you think you'll need more time, or are expecting to do more hardware or software work at that time, we should talk about it in more detail.

I notice that Dave Osip is on vacation until after the 27th and that Jim and Julie aren't going to arrive at the observatory until early June so nobody will be at the observatory to work on the computer anyway. Is it OK to delay the shipment of the MagIC Sun computer until then? If so, we would need the shipment from you by Monday, May 16, 2005.
