are employed for terminating the
flight of the balloon envelope; and
(3) The balloon envelope is equipped
with a radar reflective device(s) or material that will present an echo to surface radar operating in the 200 MHz to
2700 MHz frequency range.
The operator shall activate the appropriate devices required by paragraphs
(a) (1) and (2) of this section when
weather conditions are less than those
prescribed for operation under this subpart, or if a malfunction or any other
reason makes the further operation
hazardous to other air traffic or to persons and property on the surface.
(b) No person may operate an unmanned free balloon below 60,000 feet
standard pressure altitude between
sunset and sunrise (as corrected to the
altitude of operation) unless the balloon and its attachments and payload,
whether or not they become separated
during the operation, are equipped with
lights that are visible for at least 5
miles and have a flash frequency of at
least 40, and not more than 100, cycles
per minute.
(c) No person may operate an unmanned free balloon that is equipped
with a trailing antenna that requires
an impact force of more than 50 pounds
to break it at any point, unless the antenna has colored pennants or streamers that are attached at not more than
50 foot intervals and that are visible
for at least one mile.
(d) No person may operate between
sunrise and sunset an unmanned free
balloon that is equipped with a suspension device (other than a highly conspicuously colored open parachute)
more than 50 feet along, unless the suspension device is colored in alternate
bands of high conspicuity colors or has
colored pennants or streamers attached
which are visible for at least one mile.

(2) The estimated date and time of
launching, amended as necessary to remain within plus or minus 30 minutes.
(3) The location of the launching site.
(4) The cruising altitude.
(5) The forecast trajectory and estimated time to cruising altitude or
60,000 feet standard pressure altitude,
whichever is lower.
(6) The length and diameter of the
balloon, length of the suspension device, weight of the payload, and length
of the trailing antenna.
(7) The duration of flight.
(8) The forecast time and location of
impact with the surface of the earth.
(b) For solar or cosmic disturbance
investigations involving a critical time
element, the information in paragraph

30 minutes to 24 hours before beginning
the operation.
(c) Cancellation notice: If the operation is canceled, the person who intended to conduct the operation shall
immediately notify the nearest FAA
