Please see the message below regarding a request for optical tracking of today’s planned Electron launch with NABEO. - TS Dr. T.S.

We should get downlink data of the sail deployment but is a risk that the aluminium coated foil blocks the signal of the antenna. Therefore we came up with the idea to maybe try to see if someone in the amateur astronomy community would like to give it a try to get a picture of the sail (2.5m2 sail area in a 500km orbit) from the ground once the dragsail is deployed (1.5hr after launch (launch currently scheduled at 0:30 UTC on the 23rd of June). More infos to the sail (NABEO): www.hps-gmbh.com/ADEO/<http://www.hps-gmbh.com/ADEO/> Please find attached the state vector for the deployment (according to the current launch time (TBD)). We though maybe you have someone in mind that would be interested to try to get a nice picture of the kick-stage with the dragsail once its orbiting the earth.
